실험 절차
To 6-(4-chlorophenyl)-7-fluoro-1-methyl-4H-isoxazolo[4,5-e]pyrido[3,4-c]azepine (0.020 g, 0.061 mmol) was added a solution of methylamine (33% in EtOH) (4 mL) at room temperature. The reaction was heated to 80° C. for 22 h before silica gel was added. The solvent was removed under vacuum, the dry silica gel was packed and the adsorbed product was purified by flash chromatography (hexane/EtOAc 8:2 to 2:8) to give 6-(4-chlorophenyl)-N,1-dimethyl-4H-isoxazolo[5,4-c]pyrido[4,3-e]azepin-7-amine as a white solid (0.014 g). 1H NMR (400 MHz, DMSO-d6) δ 8.27 (d, J=5.26 Hz, 1H), 7.35 (td, J=2.30, 8.93 Hz, 2H), 7.30 (td, J=2.30, 8.93 Hz, 2H), 6.93 (d, J=5.26 Hz, 1H), 5.87 (q, J=4.35 Hz, 1H), 5.22 (d, J=12.82 Hz, 1H), 4.03 (s, 1H), 2.61 (d, J=4.58 Hz, 3H), 2.50 (s, 3H); LC/MS m/z 339 [M+H]+.
