    Abstract: There is provided a process for preparing a pharmacologically acceptable salt of N-(1(S)-ethoxycarbonyl-3-phenylpropyl)-L-alanyl-amino acid which comprises condensing an amino acid and N-(1(S) -ethoxycarbonyl-3-phenylpropyl)-L-alanine N-carboxy-anhydride under basic condition, carrying out decarboxylation under between neutral and acidic condition to obtain N-(1(S)-ethoxycarbonyl-3-phenylpropyl)-L-alanyl-amino acid, and forming a pharmacologically acceptable salt thereof, wherein the production of a by-product (3): is suppressed by carrying out in an aqueous liquid a series of operations till formation of the pharmacologically acceptable salt or till isolation of the pharmacologically acceptable salt. The present invention enables to prepare the pharmacologically acceptable salt of N-(1(S)-ethoxycarbonyl-3-phenylpropyl)-L-alanyl-amino acid having high quality, in a commercial scale with high yield and economical efficiency.

  • Patent number: 6515179
    Abstract: A 2- or 4-nitrobenzenesulfonamide is allowed to react with an alkali metal alkoxide to remove a nitrobenzenesulfonyl group to thereby obtain an amine corresponding to the amide. Furthermore, a method for producing an amine derivative by allowing the resulting amine without isolation to react with an activated, substituted oxycarbonyl compound or an activated acyl compound is provided. According to this method, a corresponding free amine and its substituted derivative can be produced easily and industrially advantageously from the 2- or 4-nitrobenzenesulfonamide without using a thiol compound.
