Reaction Steps

A The reaction is carried out in a way analogous to that described in Example 2A, but from 1.6 g of benzyl (2RS,4RS,5RS)-3-{3-[2-(2-(3,3-dimethylpiperidino)carbonyl-5-(2-fluorophenyl)-4-phenylsulphonyl-1-pyrrolidinyl)-2-oxoethyl]ureido}benzoate and 0.15 g of 10% palladium-on-charcoal in 100 cm3 of ethanol. After treatment, there is obtained 0.35 g of (2RS,4RS,5RS)-3-{3-[2-(2-(3,3-dimethylpiperidino)carbonyl-5-(2-fluorophenyl)-4-phenylsulphonyl-1-pyrrolidinyl)-2-oxoethyl}ureido}benzoic acid, melting at 258° C.
