실험 절차
To a mixture of 2-nitro 6,7,8,9-tetrahydro-5-thia-8-aza-benzocycloheptene (1.0 g, 0.0047 mol), hydrazine hydrate (10 mL) in ethanol (40 mL) was added 10% palladium on carbon (0.2 g) and refluxed 3 days, filtered and concentrated to give 6,7,8,9-tetrahydro-5-thia-8-aza-benzocyclohepten-2-ylamine (0.76 g, 90%) as a yellow solid. MP: 110-111° C.; 1H-NMR (DMSO-d6) δ 7.08-15 (d, 1H), 6.45 (s, 1H), 6.25-33 (d, 1H), 5.15 (s, 2H), 3.78 (s, 2H), 3.10-20 (m, 2H), 2.50-60 (m, 2H), 2.00-22 (br, 1H); LC/MS (ESI+): 181 (M+H).
