Procedure

N-(N-Acetyl-S-ethyl-L-cysteinyl)pyrrolidine was synthesized in exactly the same manner as described in Example 14 except that the S-methyl-N-acetyl-L-cysteine and aqueous 70% ethylamine solution used in that example were replaced by S-ethyl-N-acetyl-L-cysteine and pyrrolidine, respectively.
