13.1 g (40 mMole) N-(2'-nitrophenyl)-4-isobutyrylaminobenzamide are hydrogenated under standard conditions in 400 mL tetrahydrofuran in the presence of 10% palladium charcoal. After concentrating the solvent to 120 mL, the precipitated crystals are filtered off with suction. Yield 10.2 g (86% of theory); m.p. 247.6° C.
