실험 절차

Under H2, N,N-dimethyl-4-nitrobenzenesulfonamide (879 mg, 3.8 mmol, 1.0 equiv.) was catalytically hydrogenated in the presence of Pd/C (40 mg) in MeOH (25 mL). When no more H2 was consumed, the reaction mixture was filtered. The filtrate was concentrated and crystallized to afford compound 4-amino-N,N-dimethyl benzenesulfonamide (722 mg, 95%).
