Reaction Steps

A The reaction is carried out in a way analogous to that described in Example 2A, but from 3.6 g of benzyl (2RS,4SR,5RS)-3-{3-[2-(2-tert-butoxycarbonyl-5-(2-fluorophenyl)-4-phenylsulphonyl-1-pyrrolidinyl)-2-oxoethyl]ureido}phenylacetate 0.4 g of 10% palladium-on-charcoal in 200 cm3 of ethanol. After treatment, there are obtained 1.45 g of (2RS,4SR,5RS)-3-{3-[2-(2-tert-butoxycarbonyl-5-(2-fluorophenyl)-4-phenylsulphonyl-1-pyrrolidinyl)-2-oxoethyl]ureido}phenylacetic acid [Rf =0.27; eluent: methylene chloride/methanol (80/20)].
