DOSAGE: 3.0 - 4.5 mg.
DURATION: 8 - 15 h.
QUALITATIVE COMMENTS: (with 3.0 mg) There was an amphetamine-like stimulation that was apparent an hour into it, and considerable anxiety. I had stomach cramps, but there were indications that there might be something hallucinogenic at a higher dose.
(with 4.5 mg) An enhancement of color perception, and some auditory distortion, that was still noticeable some eight hours into the experience. The visual changes were intense. I felt I was running a slight fever, and was restless, but there was almost no physical malaise. I was still somewhat wound up even at the 14th hour.
EXTENSIONS AND COMMENTARY: These qualitative comments are not true quotations, but have been reconstructed from the published summaries of the human trials reported by several South American researchers. I have personally never tasted DON and have only these fragments from which to create a portrait of activity. A brief quotation, from a note published by these researchers in a bulletin that is restricted to forensic scientists serving law enforcement agencies, is certainly subject to a number of interpretations. It reads as follows: RThis action [a strong stimulant action reminiscent of amphetamine] seems to reduce the incidence of insightful, and therefore potentially unpleasant experiences, and thus [DON seems likely] to appear on the market as an illicit recreational drug.S I must admit that I have tried, and I am still not able, to interpret this quotation.
71 DOPR; 2,5-DIMETHOXY-4-(n)-PROPYLAMPHETAMINE
SYNTHESIS: A suspension of 285 g mossy zinc in 285 mL H2O containing 5.7 g mercuric chloride was treated with 285 mL concentrated HCl and shaken as needed to effect amalgamation. The H2O was then drained off, the zinc washed with fresh water and drained again. There was added a solution of 74 g 2,5-dimethoxypropiophenone (from the reaction of propionic acid and p-dimethoxybenzene in the presence of polyphosphoric acid, see under DOAM for an effective general procedure) in 140 g EtOH. The reaction mixture was held at reflux for 24 h with the periodic addition of concentrated HCl. It was then cooled, diluted with H2O and CH2Cl2, and the organic phase separated.
The aqueous phase was extracted with 2x100 mL additional CH2Cl2. The combined organic phases were washed with 5% NaOH until the washes remained basic, once with H2O, and then the solvent was removed under vacuum. The residue was distilled at the water pump, giving an early fraction quite rich in starting p-dimethoxybenzene, and a second fraction (61 g, bp 140-160 !C) which was free of carbonyl group by infra-red, and which was largely 2,5-dimethoxypropylbenzene. It was used without further purification in the following aldehyde synthetic step.
A mixture of 124 g N-methylformanilide and 140 g POCl3 was allowed to stand until there was the development of a strong red color. There was then added 60 g of the above 2,5-dimethoxypropylbenzene and the mixture was held on the steam bath for 2 h. The mixture was added to 2 L H2O and stirred until the excess acid chloride had completely decomposed. The mixture was extracted with 3x100 mL CH2Cl2 and, after the removal of the solvent from the combined extracts, the residue was extracted with 3x100 mL boiling hexane. Removal of the solvent gave the product 2,5-dimethoxy-4-propylbenzaldehyde as an oil, 23 g, which was characterized as its malononitrile derivative. Equal weights of the product and malononitrile in EtOH with a catalytic amount of triethylamine gave yellow crystals which, on recrystallization from toluene, had a mp of 113-114 !C.
A solution of 21.5 g of the above crude 2,5-dimethoxy-4-propylbenzaldehyde in 75 g acetic acid, was treated with 10.4 g nitroethane and 6.6 g anhydrous ammonium acetate. This was heated on the steam bath for 1.75 h, then cooled and diluted with H2O to the point of turbidity. With long standing and scratching, there finally was the deposition of crystals which were removed by filtration and sucked as dry as possible. This 23 g of crude product cake was triturated under MeOH, filtered again, and air dried to give 11 g of dull orange crystals. Recrystallization from boiling MeOH
gave 1-(2,5-dimethoxy-4-(n)-propylphenyl)-2-nitropropene as fine orange crystals which weighed, after filtering, washing, and drying, 7.4 g, and which had a mp of 94-96 !C.
To a suspension of 6.0 g LAH in 500 mL anhydrous Et2O, which was being stirred and also held as a gentle reflux, there was added a saturated solution of (2,5-dimethoxy-4-(n)-propylphenyl)-2-nitropropene in warm THF. The reaction mixture was held at reflux for 24 h, then cooled to room temperature. The excess hydride was destroyed by the cautious addition of 500 mL dilute H2SO4. The phases were separated, and the aqueous phase washed with additional Et2O. There was then added 150 g potassium sodium tartrate, and the pH was brought to >9 with aqueous NaOH. The product was extracted with Et2O and, after removal of the solvent, the residue was dissolved in 200 mL anhydrous Et2O and saturated with anhydrous HCl gas. The solids that formed were removed by filtration, giving 6.15 g 2,5-dimethoxy-4-(n)-propylamphetamine hydrochloride (DOPR) as an electrostatic, white crystalline powder, with a mp of 182.5-183 !C. This was not improved by recrystallization from either IPA or CH3CN.
DOSAGE: 2.5 - 5.0 mg.
DURATION: 20 - 30 h.
QUALITATIVE COMMENTS: (with 2.0 mg) The onset is slower than any other thing I can think of. There was nothing at all at the end of an hour, and only a threshold a half hour later. By the middle of the third hour, I was up to 1+, and that seemed to be about as high as it intended to take me. Attempts to sleep at the ninth hour were not successful, as there were strange patterns of not-quite logical thinking going on. Stuff like: TThe block events (like a babyUs rectangular building blocks) that were gotten, along with other things, from the full octaves of the left hand in Listz's Hungarian Rhapsody, events that allowed an easy recognition of the odds of achieving successful re-entry from any of several erotic codes.U
Clearly this was not a baseline state. After six hours of successful sleep, I was still off-baseline , and on into the following day. Go on up with curiosity but with caution.
(with 3.6 mg) Imagery that was constructed in response to the music turned out to be necessary to organize and contain it. The trio is the nucleus that transforms the written to the heard, but it has created its own bubble without connections to the real world, and must play on and on and on to keep itself afloat and never touching the stage again.
(with 5.0 mg) I am now at midnight, and still strongly +++. This is certainly maximum dosage, at least for a long time. There are faint intimations of nervous system scrungies. You know, the kind of thing that makes you figure it's going to be a while before youUll try to relax into sleep. This material, like all the other DOUs, is a heavy duty psychedelic, the kind that says to you, 'Forget all that stuff about screening out visuals,' and then proceeds to prove it. Sort of indole-like in that way. Your body as well as your mind tells you youUre into it, baby, and better relax and enjoy the trip, because youUve left the shore way behind. When it was time for bed, I got to sleep with surprising ease, and slept for only about six hours. My dreams were excellent, balancing, and good humored. But the next day I realized I was still carrying the DOPR in me, and that baseline was definitely not there. But it was OK. No problems except for sleepiness. The next evening I went to bed at unheard-of hour of 9 PM
and slept for 13 hours, give or take. Fascinating compound, but I wonUt go out of my way to take it again soon.
EXTENSIONS AND COMMENTARY: There is a thread of disconnection and of inconsistent reference that pervades most of the reports that I have received concerning the use of DOPR. The word that comes to mind is hypnogogic. There is a drifting into that place that lies between a not-quite-awake and a not-quite-asleep state seems to characterize this compound. There is no question but that it is very potent, and that it is very long-lived. But there is a nagging suggestion of the out-of-body, out-of-center character that is the hallmark of the anesthetic and delusional drugs such as scopolamine or ketamine. With them, the psychedelic effects become clouded with touches of amnesia.
If DOPR shows this with it's three carbon alkyl group, thereis every reason to pay close attention as the chain becomes longer.
There
had been quite a bit of speculation in the literature that the metabolic attack on DOM was at the 4-position, and this was an oxidation process. In a moment of inspiration, I decided to explore a similar oxidation step in DOPR, since it is probably the most potent of the DO-series. Why not make the compound which would be the first step in this oxidation, the 1-hydroxypropyl analogue? This I did, by using the phthalimide derivative of 2,5-dimethoxyamphetamine (described in the synthesis of DOI) and making the propiophenone using propionic acid as both reagent and solvent, and polyphosphoric acid as the condensing agent. The ketone product (a white crystalline solid from methanol) was dissolved in warm methanol and reduced to the alcohol with sodium borohydride. This product, also a white crystalline solid, was stripped of the phthalimide blocking group with overnight refluxing with hydrazine in ethanol. The product, 2,5-dimethoxy-4-(1-hydroxypropyl)-amphetamine (hydroxy-DOPR) had a mp of 148-150 !C from IPA. Its activity is not yet known, but there were no effects at all at trials, orally, of up to 200 micrograms.
But this is all with the normal-propyl compound. There is a rich collection of misinformation and potential discovery that is associated with the isopropyl isomer. This structural isomer, 2,5-dimethoxyl-4-(i)-propylamphetamine is properly called DOIP for des-oxy-iso-propyl. It has been synthesized and explored in animals and, to a modest extent, in man. The synthesis has proceeded from 2,5-dimethoxyacetophenone by the addition of a methyl group to the carbonyl followed by reduction to the hydrocarbon. Aldehyde formation, nitropropene synthesis with nitroethane, and lithium aluminum hydride reduction are uneventful, providing the hydrochloride salt DOIP, which has a mp of 183-184 !C as an analytical sample.
Animal tests (such as rabbit hyperthermia assays), have indicated that the isopropyl compound DOIP is less potent than the propyl prototype, DOPR, by between one and two orders of magnitude. In man, a dose of four milligrams, a rousing dose of DOPR, is without any effects. At 10 milligrams, there is some disturbance but substantially no effects.
I have been told that with doses in the 20 to 30 milligram range there are valid changes in mental state, but I have not been told the nature of these changes.
A fascinating red herring had been drawn across all of these exacting lines by a strange visitor to this research project. An olive-faced M.D., Ph.D., passed through this confusing scene briefly, and when he left, a small supply of DOPR left with him. He promptly published in an obscure journal some animal behavioral responses which he ascribed to the isopropyl analogue, DOIP. But what he had studied could only have been DOPR since DOIP, at that time, had not yet been synthesized either by me, or by either of the other two active synthesists of that moment. It was not yet a known material. We all made it some time later, but by that time our olive-face had disappeared. There is a magnificent French phrase that applies here as nowhere else; Il a foutu le camp. Its idiomatic meaning is equivalent to our, RHe took off,S or RHe split the scene,S but the literal translation is, RHe fucked the camp.
72 E; ESCALINE; 3,5-DIMETHOXY-4-ETHOXYPHENETHYLAMINE
SYNTHESIS: To a solution of 72.3 g 2,6-dimethoxyphenol in 400 mL MeOH, there was added 53.3 g of a 40% solution of aqueous dimethylamine folowed by 40 g of a 40% aqueous solution of formaldehyde. The dark solution was heated under reflux for 1.5 h on a steambath. The volatiles were then removed under vacuum yielding a dark oily residue of 2,6-dimethoxy-4-dimethylaminomethylphenol. This residue was dissolved in 400 mL of IPA, to which there was added 50 mL of methyl iodide. The spontaneously exothermic reaction deposited crystals within 3 min, and was allowed to return to room temperature and occasionally stirred over the course of 4 h. The solids were removed by filtration, washed with cold IPA, and allowed to air dry yielding 160 g of the methiodide of 2,6-dimethoxy-4-dimethylaminomethylphenol as a cream-colored crystalline solid.
A suspension of 155 g of the above methiodide of 2,6-dimethoxy-4-dimethylaminophenol in 600 mL H2O was treated with a solution of 130 g KCN in 300 mL H2O. The reaction mixture was heated on a steam bath for 6 h during which time there was a complete dissolving, the development of a brownish color with a bright blue film on the surface and the walls of the flask, and the gentle evolution of fine gas bubbles. The hot reaction mixture was poured into 1.2 L H2O and acidified with concentrated HCl (careful, HCN
evolution). The aqueous solution was extracted with 3x150 mL CH2Cl2, the extracts pooled, washed with saturated NaHCO3 which removed much of the color. The solvent was removed under vacuum yielding about 70
g of a viscous black oil. This was distilled at 0.4 mm/Hg at 150-160
!C to provide 52.4 g of homosyringonitrile (3,5-dimethoxy-4-hydroxyphenylacetonitrile) as a white oil that spontaneously crystallized to lustrous white crystals that melted at 57-58 !C.
A solution of 5.75 g of homosyringonitrile and 12.1 g ethyl iodide in 50 mL dry acetone was treated with 6.9 g finely powdered anhydrous K2CO3 and held at reflux for 18 h. The mixture was diluted with 100
mL Et2O, filtered, and the filtrate solvent removed under vacuum The residue was recrystallized from Et2O/hexane to yield 5.7 g 3,5-dimethoxy-4-ethoxyphenylacetonitrile with a mp 57-58 !C. Anal.
(C12H15NO3) C,H,N.
A solution of 2.21 g 3,5-dimethoxy-4-ethoxyphenylacetonitrile in 25 mL
EtOH containing 2.5 mL concentrated HCl and 400 mg 10% palladium on charcoal, was shaken in a 50 lb/sq.in. atmosphere of hydrogen for 24
h. Celite was added to the reaction suspension and, following filtration, the solvents were removed under vacuum. The residue was recrystallized from IPA/Et2O to yield 2.14 g 3,5-dimethoxy-4-ethoxyphenethylamine hydrochloride (E) with a mp of 166-167 !C.
Synthesis from syringaldehyde: A well-stirred suspension of 21.9 g syringaldehyde in 45 mL H2O was heated to reflux in a heating mantle.
There was then added a solution of 15 g NaOH in 60 mL H2O. The heating and stirring was continued until the generated solids redissolved. Over a period of 10 min, there was added 23 g diethyl sulfate, then refluxing was continued for 1 h. Four additional portions each of 5 g diethyl sulfate and of 6 mL 20% NaOH were alternately added to the boiling solution over the course of 2 h. The cooled reaction mixture was extracted with Et2O, the extracts pooled and dried over anhydrous MgSO4, decolorized with Norite, and stripped of solvent. The crude 3,5-dimethoxy-4-ethoxy-benzaldehyde weighed 21.8 g and melted at 51-52 !C.
A solution of 14.7 g 3,5-dimethoxy-4-ethoxybenzaldehyde and 7.2 mL
nitromethane in 50 mL glacial acetic acid was treated with 4.4 g anhydrous am-monium acetate and held at reflux for 30 min. Cooling the reaction allowed the formation of yellow crystals which were removed by filtration and washed sparingly with cold acetic acid. The dried 3,5-dimethoxy-4-ethoxy-'-nitrostyrene weighed 11.5 g and melted at 108-109 !C after recrystallization from EtOH Anal. (C12H15NO5) C,H.
Alternately, this product may be prepared from 3.9 g.
3,5-dimethoxy-4-ethoxybenzaldehyde in 60 mL nitromethane containing 0.7 g ammonium acetate and heated on a steam bath for 1 h. The solvent was removed under vacuum, and the residue dissolved in a minimum of hot MeOH. Cooling provided, after filtration and air drying, 2.3 g of bright yellow crystals of 3,5-dimethoxy-4-ethoxy-'-nitrostyrene, with a mp of 105-107 !C.
A solution of 2.25 g LAH in 45 mL anhydrous THF was vigorously stirred and cooled to 0 !C under He. There was added 1.5 mL 100% H2SO4
dropwise, followed by 2.3 g 3,5-dimethoxy-4-ethoxy-'-nitrostyrene in anhydrous THF. After the addition was complete, the mixture was allowed to stir for 30 min, and then brought to room temperature. The unreacted hydride was decomposed with 2.3 mL H2O in THF, followed by the addition of 9.2 mL of 15% NaOH. The white suspension was filtered, the filter cake was washed with THF, the filtrate and washings combined, and the solvent removed under vacuum. The residue was dissolved in 300 mL dilute H2SO4, washed with 2x75 mL CH2Cl2, made basic with 25% NaOH, and the product extracted with 3x75 mL CH2Cl2.
After removal of the solvent, the residue was distilled at 110-120 !C
at 0.3 mm/Hg yielding 1.
4 g of a colorless oil. A solution of this oil in 20 mL IPA was neutralized with 17 drops of concentrated HCl and diluted with 100 mL anhydrous Et2O. After a few minutes there was the spontaneous formation of white crystals of 3,5-dimethoxy-4-ethoxyphenethylamine hydrochloride (E) which was recrystallized from 40 mL boiling EtOAc containing 1 mL MeOH. The mp was 165-166 !C.
DOSAGE: 40 - 60 mg.
DURATION: 8 - 12 h.
QUALITATIVE COMMENTS: (with 40 mg) This is a powerful and complex intoxicant Q I could not have coordinated any rational muscular activity. I could not walk; I could not tie my shoe-laces. There is analgesia and an incoordination that I cannot shake. My menstrual flow started a bit ahead of time, but it was light.
(with 50 mg) I felt that the body tensions outweighed the psychological and sensory rewards, in that I had a lot of dehydration and my sleep had a nightmare quality. This pretty much offset the few virtues that I felt I had obtained.
(with 60 mg) There is a quality of rational analysis and insight that is totally impressive. Many subtle factors in my life can be viewed with insight, and usefully dissected. I got into a deep discussion, but I was not argumentative or even defensive and I remained detached and kept a tone of cool impersonality. I had a good appetite. But I also had some tachycardia and muscular tension. There was unquestionable sensory enhancement, but without an intellectual component. Overall it was most pleasant.
EXTENSIONS AND COMMENTARY: In an isolated situation, there is easy fantasy, but little synthesis of external sensory inputs such as music or visual stimulae. A gradual decline brings the subject back to a restful baseline somewhere before the 12th hour. The following day is often seen as one of tiredness and low energy. An anonymous flyer appeared in the California drug community in 1984 stating an effective range to be 50 to 100 milligrams, but it described the drug as the sulfate. The above data all pertain to the hydrochloride salt.
