実験手順
A mixture of 1-(8-nitro-2,3,4,5-tetrahydro-benzo[b]azepin-1-yl)-ethanone (1.3 g, 5.4 mmol) and Pd—C (10%, 100 mg) in EtOH (200 mL) was stirred under H2 (1 atm) at room temperature for 1.5 h. The mixture was filtered through a layer of Celite and the filtrate was concentrated to give 1-(8-amino-2,3,4,5-tetrahydro-benzo[b]azepin-1-yl)-ethanone (DC-9) as a white solid (1 g, 90%). 1H NMR (CDCl3) δ 7.01 (d, J=6.0 Hz, 1 H), 6.56 (dd, J=6.0, 1.8 Hz, 1 H), 6.50 (d, J=1.8 Hz, 1 H), 4.66-4.61 (m, 1 H), 3.50 (br s, 2 H), 2.64-2.55 (m, 3 H), 1.94-1.91 (m, 5 H), 1.77-1.72 (m, 1 H), 1.32-1.30 (m, 1 H); ESI-MS 204.1 m/z (MH+).
