It is an analogue of the major human neurotransmitter dopamine where the 3- and 4-position hydroxy groups have been replaced with methoxy groups. It is also closely related to mescaline which is 3,4,5-trimethoxyphenethylamine. ==Chemistry== One of the earliest syntheses of DMPEA (then referred to as "homoveratrylamine") was that of Pictet and Finkelstein, who made it in a multi-step sequence starting from vanillin.〔A. Pictet and M. Finkelstein (1909). "Synthese des Laudanosins." ''Ber.'' 42 1979-1989.〕 A similar sequence was subsequently reported by Buck and Perkin,〔J. S. Buck and W. H. Perkin (1924). "CCXVIII. Ψ-epiBerberine." ''J. Chem. Soc., Trans.'' 125 1675-1686.〕 as follows: :3,4-Dimethoxybenzaldehyde (veratraldehyde) → 3,4-Dimethoxycinnamic acid → 3,4-Dimethoxyphenylpropionic acid → 3,4-Dimethoxyphenylpropionamide → 3,4-Dimethoxyphenethylamine A much shorter synthesis is given by Shulgin and Shulgin:〔A. Shulgin and A. Shulgin (1991). "PiHKAL A Chemical Love Story", pp. 614-616, Transform Press, Berkeley. ISBN 0-9630096-0-5〕〔(【引用サイトリンク】 Erowid Online Books : "PIHKAL" - #60 DMPEA )〕 3,4-Dimethoxybenzaldehyde is reacted with nitromethane in the presence of ammonium acetate/acetic acid to give the corresponding β-nitrostyrene, which is then reduced with LiAlH4 to give 3,4-dimethoxyphenethylamine. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「3,4-Dimethoxyphenethylamine」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
