A suspension of give 4-amino-N-(3,4-dimethyl-phenyl)-3-nitro-benzamide (560 mg) and platinum oxide (50 mg) in ethanol (50 mL) was hydrogenated at 50 psi for 3 h. The catalyst was filtered through Celite and the filtrate evaporated to give 3,4-diamino-N-(3,4-dimethylphenyl)-benzamide as a brownish foam; MS (m/z) 256 (M+1).
