실험 절차

To a solution of 4-(3-acetyl-6-bromo-1-oxo-4-phenyl-1H-isoquinolin-2-ylmethyl)benzoic acid (476 mg) in dichloromethane (10 ml) were added O,N-dimethylhydroxylamine hydrochloride (117 mg), 1-hydroxy-1H-benzotriazole (184 mg) and triethylamine (0.21 ml) and then 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (287 mg) was added at room temperature, and the mixture was stirred at room temperature for 15 hrs. Dichloromethane was added, and the mixture was washed with saturated aqueous sodium hydrogen carbonate solution and saturated brine and sodium sulfate was added to dry the mixture. The solvent was evaporated under reduced pressure and the obtained residue was purified by silica gel column chromatography (n-hexane/ethyl acetate=1/1→1/9) to give the title compound (407 mg, 78%).
