Mescaline → 2-Formyl-3,4,5-trimethoxy-phenylethylamine

Participants

Reaction Steps

1.422 kg of 3,4,5-trimethoxy-phenylethylamine is slowly added to a mixture of 2.185 kg of 98% formic acid and 1.728 kg of acetic anhydride, while maintaining the temperature at about 50°. The reaction bath is maintained at this temperature for about 3 hours and the formic acid and acetic acid mixture and the excess anhydride is distilled. The formylated derivative thus obtained (1.734 kg) is used unpurified.
