実験手順
A solution of 4-methyl-3-nitrobenzenesulfonamide (2.1 g) and platinum oxide (210 mg) in methanol (50 ml) was stirred under hydrogen atmosphere at room temperature for 6 hours. The insoluble compound was filtered out, then the filtrate was concentrated. The residue was recrystallized from hexane/acetone to obtain the title compound (1.23 g).
