A process for the racemization of optically active amines of the formula (I), where Ar is an unsubstituted or substituted aryl and R is alkyl, in which a) (I) is reacted with the ketone (II) in which Ar and R have the same meanings as for (I), to give the condensation product (III), (see fig. I) (see fig. II) (see fig. III) b) (III) is racemized by treatment with base, (see fig. III) (see fig. rac.III) c) the arylalkylamine (I) is liberated as racemate from racemic (III) by reaction with optically active (I). (see fig. rac. III) + (see fig. I) (see fig. III) + (see fig. I)
