To a mixture of N-methyl-4-(4-morpholinyl)-3-nitrobenzenesulfonamide (2.5 g, 8.30 mmol) in THF (100 mL) under nitrogen, Pd/C (0.8 g) was added. The flask was then evacuated and recharged with hydrogen three times. The resulting mixture was allowed to stir under a hydrogen atmosphere at 50° C. overnight. The mixture was then filtered and concentrated to afford 3-amino-N-methyl-4-(4-morpholinyl)benzenesulfonamide (1.98 g, 88%). 1H NMR (400 MHz, DMSO-d6) δ 7.07-7.17 (m, 2H), 7.01 (d, J=8.28 Hz, 1H), 6.94 (dd, J=1.88, 8.16 Hz, 1H), 5.20 (s, 2H), 3.72-3.81 (m, 4H), 2.80-2.89 (m, 4H), 2.38 (d, J=4.77 Hz, 3H); MS (m/z) 272.2 (M+H+)
