Abstract
Process for the preparation of 1- (3 ', 4'-dimethyl-phenyl) -2-amino-propane and its acid addition salts, characterized by diazearing 1-amino-3,4-dinotylbenzene, reacting the compound of resulting diazonium with formaldoxin, to form 3,4-dimethyl-benzaldoxime, hydrolyzed this to obtain 3,4-dimethyl-benzaldehyde, condensing the latter with nitroethane to form 3,4-beta-trimethyl-beta-nitro-styrene, reducing said 3,4-beta-trimethyl-beta-nitro-styrene to 1- (3 ', 4'-dimethyl-phenyl) -2-amino-propane and, if desired, convert it into an acid addition salt.
