実験手順

1-Methyl-7-nitro-2,3,4,5-tetrahydro-1H-benzo[b]azepine (135 mg, 0.66 mmol) in a solution of ethanol (4 mL) and hydrazine hydrate (1 mL) was treated with 10% palladium on carbon (40 mg) and heated at 60° C. for 2 h. The mixture was cooled to room temperature, filtered and concentrated to give 1-Methyl-2,3,4,5-tetrahydro-1H-benzo[b]azepin-7-ylamine (110 mgs, 96%) as a grayish oil. 1H-NMR (CDCl3) δ 6.78-6.72 (m, 1H), 6.51 (s, 2H), 3.38 (br s, 2H), 2.82-2.74 (m, 7H), 2.21-2.15 (m, 2H), 1.75-1.68 (m, 2H), 1.57-1.52 (m, 2H); LC/MS (ESI+): 177.16 (M+H).
