Patent number: 6046351Abstract: The invention concerns a novel process for preparing racemic phenethylamines of formula (I) ##STR1## in which R.sup.1, R.sup.2, R.sup.3, R.sup.4 and R.sup.5 have the meanings given in the description. According to this process: a) in a first step, optically active phenethylamines of formula (I*) ##STR2## are reacted with acetophenone derivatives of formula (II), ##STR3## the optically active phenethylamine used and the acetophenone derivative used each being substituted in an identical manner in the phenyl part, optionally in the presence of a diluting agent and optionally in the presence of a catalyst; b) in a second step, the resultant optically active Schiff bases of formula (III*) ##STR4## are reacted with metallic hydroxides containing between 0.1 and 50 wt. % water; and c) in a third step, the resultant racemic Schiff bases are reacted with acids in the presence of water.Type: GrantFiled: January 19, 1999Date of Patent: April 4, 2000Assignee: Bayer AktiengesellschaftInventor: Uwe Stelzer
