실험 절차

10 g of 7-chloro-6-fluoro-2H-isoquinolin-1-one (60) were suspended in 100 mL of DMF. 19.75 g of cesium carbonate and 7.55 mL of p-methoxy benzyl chloride were added successively and the mixture was stirred for 2 h. The mixture was poured on ice/water and the formed precipitate was filtered off, washed with water and dried in vacuum to give 13.67 g of the title compound. Rt=1.96 min (Method B). Detected mass: 318.1 (M+H+).
