실험 절차
To a solution of N-(2-nitrophenyl)methanesulfonamide (800 mg, 3.70 mmol) in methanol (20 mL) was added palladium on carbon (10% by weight, 394 mg, 0.37 mmol). The vessel was purged with hydrogen and then stirred for 4 hours under 1 atm of hydrogen. The reaction was filtered, concentrated and purified by chromatography to provide N-(2-aminophenyl)methanesulfonamide (600 mg, 87% yield). 1H NMR (300 MHz, DMSO-d6) δ 8.67 (bs, 1H), 7.05 (dd, J=7.8, 1.5 Hz, 1H), 6.98 (m, 1H), 6.73 (dd, J=7.8, 1.5 Hz, 1H), 6.54 (m, 1H), 5.11 (bs, 2H), 2.90 (s, 3H).
