摘要:
An N-alkoxycarbonyl-N-cyanoethyl amino acid alkyl ester is produced at a high yield by reacting a mineral acid salt of amino acid alkyl ester with acrylonitrile in an alcohol medium in the presence of an inorganic base to form an N-cyanoethyl amino acid alkyl ester and then reacting the N-cyanoethyl amino acid alkyl ester with a dialkyl dicarbonate.
