Procedure

A The reaction is carried out in a way analogous to that described in Example 3, but from 1.6 g of 2-tert-butyl 4-methyl (2RS,4RS,5SR)-1-{2-[3-(3-methylphenyl)ureido]acetyl}-5-phenylpyrrolidine-2,4-dicarboxylate and 0.18 g of potassium hydroxide in 20 cm3 of distilled water and 60 cm3 of methanol. After treatment, there is obtained 0.7 g of 2-tert-butyl hydrogen (2RS,4SR,5SR)-1-{2-[3-(3-methylphenyl)ureido]acetyl}-5-phenylpyrrolidine-2,4-dicarboxylate, melting at 160° C.
