실험 절차

A solution of 1-methanesulfonyl-4-nitro-benzene (500 mg, 2.48 mmol) in methanol (20 ml) was hydrogenated over 10% Pd—C (100 mg) at atmospheric pressure until no further gas uptake was observed. The reaction mixture was then filtered over celite and concentrated to give a residue, which was recrystallized from ethanol to yield 4-methanesulphonyl-phenylamine (276 mg, 65%) as solid.
