  • Patent number: 5144077
    Abstract: The invention relates to a process for working up to crystallization mother liquor which is obtained in the resolution of the racemate of 1-(4-chlorophenyl)-ethylamine of the formula (I) with S-(-)-N-phenylcarbamoyllactic acid of the formula (II) by removing the ethanol from the ethanolic crystallization mother liquor by distillation in a 1st step and stirring the residue which remains with tert.-butyl methyl ether or toluene in a second step and it being possible to employ the resulting crystalline salt of (R/S)-1-(4-chlorophenyl)-ethylamine and (S)-(-)-N-phenylcarbamoyllactic acid directly again for the resolution of the racemate. The (S)-form of the amine is mainly present in the mother liquor and can be racemised and added to the resolution of the racemate again.
