Phenethylamines i Have Known and Loved [Backwards][Forwards] [Main Index] #109 MDMA; MDM; ADAM; ECSTASY; 3,4-METHYLENEDIOXY-N-METHYLAMPHETAMINE SYNTHESIS: (from MDA) A solution of 6.55 g of 3,4-methylenedioxyamphetamine (MDA) as the free base and 2.8 mL formic acid in 150 mL benzene was held at reflux under a Dean Stark trap until no further H2O was generated (about 20 h was sufficient, and 1.4 mL H2O was collected). Removal of the solvent gave an 8.8 g of an amber oil which was dissolved in 100 mL CH2Cl2, washed first with dilute HCl, then with dilute NaOH, and finally once again with dilute acid. The solvent was removed under vacuum giving 7.7 g of an amber oil that, on standing, formed crhite residue which was distilled at 100-110 °C at 0.4 mm/Hg to give 5.0 g of a colorless oil. This was dissolved in 25 mL IPA, neutralized with concentrated HCl, followed by the addition of sufficient anhydrous Et2O to produce a lasting turbidity. On continued stirring, there was the deposition of fine white crystals of 3,4-methylenedioxy-N-methylamphetamine hydrochloride (MDMA) which were removed by filtration, washed with Et2O, and air dried, giving a final weight of 4.8 g. (from 3,4-methylenedioxyphenylacetone) This key intermediate to all of the MD-series can be made from either isosafrole, or from piperonal via 1-(3,4-methylenedioxyphenyl)-2-nitropropene. To a well stirred solution of 34 g of 30% hydrogen peroxide in 15 piperonal. A suspension of 32 g electrolytic iron in 140 mL glacial acetic acid was gradually warmed on the steam bath. When quite hot but not yet with any white salts apparent, there was added, a bit at a time, a solution of 10.0 g of 1-(3,4-methylenedioxyphenyl)-2-nitropropene in 75 mL acetic acid (see the synthesis of MDA for the preparation of this nitrostyrene intermediate from piperonal and nitroethane). This addition was conducted at a rate that permitted a vigorous reaction free from excessive frothing. The orange color of the reaction mixture became very reddish with the formation of white salts and a dark crust. After the addition was complete, the heating was continued for an additional 1.5 h during which t added, in succession and with swirling, 60 g methylamine hydrochloride dissolved in 60 mL warm H2O, 180 mL IPA, 145 mL 25% NaOH, 53 g 3,4-methylenedioxyphenylacetone, and finally 350 mL IPA. If the available form of methylamine is the aqueous solution of the free base, the following sequence can be substituted: add, in succession, 76 mL 40% aqueous methylamine, 180 mL IPA, a suspension of 50 g NaCl in 140 mL H2O that contains 25 mL 25% NaOH, 53 g 3,4-methylenedioxyphenylacetone, and finally 350 mL IPA. The exothermic reaction was kept below 60 °C with occasional immersion into cold water and, when it was thermally stable, it was allowed to stand until it had returned to room temperature with all the insolubles settled to the bottom as a grey sludge. The clear yting point values over the range from 148-153 °C. The variously hydrated polymorphs have distinct infrared spectra, but have broad mps that depend on the rate of heating. DOSAGE: 80 - 150 mg. DURATION: 4 - 6 h. QUALITATIVE COMMENTS: (with 100 mg) MDMA intrigued me because everyone I asked, who had used it, answered the question, 'What's it like?' in the same way: 'I don't know.' 'What happened?' 'Nothing.' And now I understand those answers. I too think nothing happened. But something seemed changed. Before the 'window' opened completely, I had some somatic effects, a tingling sensation in the fingers and temples--a pleasant sensation, not distracting. However, just after that there was a slight nan looking forward to. So I set about my several tasks with no pleasure or enjoyment and I hummed a little tune to myself during these activities which had words that went: 'I shouldn't have done that, oh yes, I shouldn't have done that, oh no, I shouldn't have done that; it was a mistake.' Then I would start over again from the beginning. I was stuck in a gray space for quite a while, and there was nothing to do but keep doing what I had to do. After about 6 hours, I could see the whole mental state disintegrating and my pleasant feelings were coming back. But so was my plain, ornery tiredness. MDMA does not work like Dexedrine. (with 120 mg) I feel absolutely clean inside, and there is nothing but pure euphoria. Itotally peaceful. I have lived all my life to get here, and I feel I have come home. I am complete. (with 100 mg of the "R" isomer) There were the slightest of effects noted at about an hour (a couple of paresthetic twinges) and then nothing at all. (with 160 mg of the "R" isomer) A disturbance of baseline at about forty minutes and this lasts for about another hour. Everything is clear by the third hour. (with 200 mg of the "R" isomer) A progression from an alert at thirty minutes to a soft and light intoxication that did not persist. This was a modest +, and I was at baseline in another hour. (with 60 mg of the "S" isomer) The effects began developing in a smooth, friendly way at about a half-houpplemental dosage of the drug at about the one and a half hour point of the session. This supplement, characteristically 40 milligrams following an initial 120 milligrams, would extend the expected effects for about an additional hour, with only a modest exacerbation of the usual physical side-effects, namely, teeth clenching and eye twitching. A second supplement (as, for instance, a second 40 milligrams at the two and a half hour point) was rarely felt to be warranted. There are, more often than not, reports of tiredness and lethargy on the day following the use of MDMA, and this factor should be considered in the planning of clinical sessions. With MDMA, the usual assignments of activity to optical isomers is brain. A wide popularization of the social use of MDMA occurred in 1984-1985 and, with the reported observation of serotonin nerve changes in animal models resulting from the administration of the structurally similar drug MDA, an administrative move was launched to place it under legal control. The placement of MDMA into the most restrictive category of the Federal Controlled Substances Act has effectively removed it from the area of clinical experimentation and human research. The medical potential of this material will probably have to be developed through studies overseas. A word of caution is in order concerning the intermediate 3,4-methylene-dioxyphenylacetone, which has also been called piperonylaparent relationship to psychedelics, psychoactives or psychotropics whatsoever. I know of one chemical supply house which supplied the weird compound, and they never did acknowledge their unusual use of the term piperonyl. There is a simple difference of properties which might be of value. The three carbon (correct) ketone is an oil with a sassafras smell that is always yellow colored. The four carbon (incorrect) ketone has a weak terpene smell and is white and crystalline. There should be no difficulties in distinguishing these two compounds. But unprincipled charlatans can always add mineral oil and butter yellow to otherwise white solids to make them into yellow oils. Caveat emptor. _________________________________________________________________ [Backwards][Forwards] [Main Index] _________________________________________________________________ HTMLized by Lamont Granquist Press RETURN to finish
