3,4-Dimethoxyphenethylamine synthesis of Bevantolol. DMPEA has some activity as a monoamine oxidase inhibitor. DMPEA occurs naturally along with mescaline in various species of cacti such as San Pedro and Peruvian Torch. 3,4-Dimethoxyphenethylamine 3,4-Dimethoxyphenethylamine (DMPEA) is a chemical compound of the phenethylamine class. 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. 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
