Procedure
0.04 g of 10% palladium-on-charcoal is added to a solution of 0.42 g of methyl ester of methyl 2(S)-(6-nitro-1-naphthoylamino)-4-(methylsulphonyl)butanoate dissolved in 30 cm3 of ethyl acetate and 20 cm3 of ethanol and the solution is subjected to a hydrogen pressure of 1.5 atmosphere for 3 hours at a temperature in the region of 20° C. The reaction mixture is filtered on sintered glass covered with Celite and concentrated to dryness under reduced pressure. 0.6 g of methyl 2(S)-(6-amino-1-naphthoylamino)-4-(methylsulphonyl)-butanoate is obtained, the characteristics of which are the following:
