실험 절차

To a solution of 4-(benzyloxy)-1-(5-methyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indol-7-yl)pyridin-2(1H)-one (0.2 g, 0.5 mmol) in CH2Cl2 (6 mL) was added triethylamine (0.20 mL, 1.4 mmol) followed by acetyl chloride (50 μL, 0.71 mmol). The reaction was stirred at room temperature until complete. After the solvent was removed under reduced pressure, the residue was purified by flash column chromatography (silica gel, 5% CH3OH in CH2Cl2) to give the title compound (72.2 mg, 36%) as a yellow solid and as a mixture of rotamers: mp 225-230° C.; 1H NMR (500 MHz, CDCl3) δ 7.53-7.36 (m, 6H), 7.32-7.30 (m, 2H), 7.06-7.00 (m, 1H), 6.09 (d, J=3.0 Hz, 1H), 6.07-6.04 (m, 1H), 5.06 (s, 2H), 4.82 (s, 1H), 4.67 (s, 1H), 4.03 (t, J=5.5 Hz, 1H), 3.84 (t, J=5.5 Hz, 1H), 3.64 (s, 3H), 2.90 (t, J=5.5 Hz, 1H), 2.84 (t, J=5.5 Hz, 1H), 2.24, 2.22 (2×s, 3H); ESI MS m/z 428 [M+H]+; HPLC (Method A) 95.7% (AUC), tR=16.8 min.
