実験手順

169 μL of p-methoxybenzylchloride (1.24 mmol, 1.1 eq) were added to a suspension of 200 mg of 6-fluoro-isoquinolinone (176) (1.13 mmol) and 368 mg of Cs2CO3 (1.36 mmol, 1.2 eq) in 3 mL of DMF. The mixture was stirred for 2 h and then poured on ice. The precipitate was filtered, washed with water and dried to yield 300 mg of the title compound. LCMS Method B, retention time 1.76 min, detected mass 284.14 [M+H]+
