A The reaction is carried out in a way analogous to that described in Example 2B but from 1.7 g of tert-butyl (2RS,4RS,5SR)-4-dimethylcarbamoyl-5-phenylpyrrolidine-2-carboxylate, 1.15 g of 2-[3-(3-methylphenyl)ureido]acetic acid and 1.15 g of N,N'-dicyclohexylcarbodiimide in 50 cm3 of acetonitrile. After treatment, there are obtained 2.2 g of tert-butyl (2RS,4RS,5SR)-4-dimethylcarbamoyl-1-{2-[3-(3-methylphenyl)ureido]acetyl}-5-phenylpyrrolidine-2-carboxylate, melting at 199° C.
