실험 절차
6-Methoxy-2-(4-methoxyphenyl)-4-phenylisoquinolin-1(2H)-one (0.36 g, 1.01 mmol) was placed in a dry 150 mL single-necked flask fitted with a stirring bar and septa. Methylene chloride (30 mL) was added via a syringe. Boron tribromide (5.0 mL of 1.0 M methylene chloride solution) was added dropwise with stirring under argon atmosphere at room temperature. The reaction mixture was allowed to stir at room temperature for 16 hours. Then, 20 mL of water was added to quench the reaction. The mixture was extracted with ethyl acetate (3×20 mL). The organic layers were separated, dried over anhydrous magnesium sulfate and concentrated under vacuum. The residue was subjected to flash column chromatography (silica gel, CH2Cl2/MeOH=9/1 v/v) to give a white solid product, 0.29 g, 87.9% yield. MS: 330.2 [M+H]+. 1H NMR (DMSO-d6, 300 MHz): δ 10.31 (s, 1H), 9.69 (s, 1H), 8.19 (d, 1H, J=8.7 Hz), 7.52-7.39 (m, 5H), 7.28 (d, 2H, J=8.7 Hz), 7.18 (s. 1H), 7.00 (dd, 1H, J1=8.7 Hz, J2=2.4 Hz), 6.87-6.82 (m, 3H).
