Reaction Steps

30 mg (0.08 mmol) of the 7-bromo-3-(2-trifluoromethylphenyl)-2H-isoquinolin-1-one prepared in Step A, 18.6 mg (0.098 mmol) of copper iodide (I), and 39.1 mg (0.204 mmol) of cesium acetate were suspended in 0.5 ml of dry dimethylformamide. Thereafter, 200 μl of a 40% methylamine-methanol solution was added to the suspension, and the obtained mixture was then stirred at 100° C. overnight. Thereafter, water was added to the reaction solution, and the mixture was then extracted with methylene chloride. The extract was washed with a saturated saline solution, and was then dried over anhydrous magnesium sulfate. The extract was concentrated. The obtained residue was purified by silica gel column chromatography (methylene chloride:methanol=100:1), so as to obtain 15.4 mg (61%) of 7-methylamino-3-(2-trifluoromethylphenyl)-2H-isoquinolin-1-one.
