    • The invention concerns a new method for producing optically active 1-phenylethylamines of formula (I*), in which X stands for halogen or methyl and n stands for the digits 0, 1 or 2, wherein (a) racemic 1-phenylethylamines of formula (I) are reacted with (S)-(-)-N-phenylcarbamate lactic acid in the presence of an aliphatic or aromatic hydrocarbon and in the presence of a lower aliphatic alcohol, wherein the reaction components are measured so that for every mol of racemic amine, between 0.25 and 0.5 mol of (S)-(-)-N-phenylcarbamate lactic acid are present, the reaction mixture is then concentrated at a liquid-phase temperature of up to 40 DEG C, the resulting solid product is separated, treated with diluted, aqueous alkaline lye in the presence of a hydrocarbon, and the respective (R)-amine is isolated by distillation from the organic phase, and if necessary, (b) the mother liquor remaining after the separation of the solid product is reacted in the presence of a lower aliphatic alcohol with (S)-(-)-N-phenylcarbamate lactic acid, wherein the reaction components are measured so that the molar quantity of (S)-(-)-N-phenylcarbamate lactic acid is twice as great as the quantity of (R)-amine still remaining in the mother liquor, the reaction mixture is then concentrated at a liquid-phase temperature of up to 40 DEG C, the resulting solid product is separated and the (S)-amine is isolated by distillation from the mother liquor.
