実験手順

Triethylamine (58 μL, 0.41 mmol), DMAP (5.0 mg, 0.041 mmol) and acetyl chloride (22 μL, 0.31 mmol) were added to a solution of 1-(6-methyl-1,2,3,4,5,6-hexahydroazepino[4,3-b]indol-8-yl)-4-(6-(trifluoromethyl)pyridin-3-yl)pyridin-2(1H)-one hydrochloride (97 mg, 0.21 mmol) in CH2Cl2 (15 mL), and the resulting solution was stirred at ambient temperature for 18 h under N2. The resulting solution was concentrated to dryness under reduced pressure. Flash chromatography (12 g ISCO column, CH2Cl2/(80:18:2 CH2Cl2/MeOH/NH4OH), 100:0 for 2 column volumes, increased to 50:50 over 20 column volumes and held for 1 column volume, then increased to 0:100 over 10 column volumes and held for 12 column volumes) gave the title compound (58 mg, 59%) as a yellow powder: mp 156-162° C.; 1H NMR (500 MHz, DMSO-d6) δ 9.19 (s, 1H), 8.49 (dd, J=8.0, 2.0 Hz, 1H), 8.05 (d, J=8.0 Hz, 1H), 7.88-7.83 (m, 1H), 7.72-7.49 (m, 2H), 7.07-6.99 (m, 2H), 6.80-6.78 (m, 1H), 4.72-4.70 (m, 2H), 3.79-3.76 (m, 2H), 3.69-3.68 (m, 3H), 3.05-2.98 (m, 2H), 2.02-1.90 (m, 5H); ESI MS m/z 481 [M+H]+; HPLC (Method A)>99% (AUC), tR=18.1 min.
