Procedure

A solution of the product of step (a) (5.7 g) in methanol (120 ml) was hydrogenolysed over 10% palladium on carbon (0.5 g) until hydrogen uptake ceased (1 hour). Activated charcoal was added and the mixture was stirred, filtered through diatomaceous earth and concentrated to give 4-(t-butoxycarbonylaminomethyl)benzoylhydrazine (3.6 g) as a colourless solid; m.p. (from toluene) 114°-116° C.; NMR Spectrum 1.4 (9H, s); 3.2-4.0 (2H, br s); 4.2 (2H, s); 7.3 (2H, d); 7.4 (1H, t); 7.8 (2H, d); 9.7 (1H, s).
