Sodium hydride → 6-Bromo-2-[(4-methoxyphenyl)methyl]-1(2H)-isoquinolinone

Participants

Reaction Steps

28.18 g (125.8 mmol) 6-Bromo-2H-isoquinolin-1-one (6) were dissolved in 200 ml Dimethylacetamide and 7.55 g (188.7 mmol) sodium hydride (60%) were added at room temperature. After stirring for 30 minutes, 29.94 g (188.7 mmol) 4-Methoxy-benzylchloride were added and stirring was continued at room temperature until complete conversion was detected. The solvent was removed under reduced pressure, the residue taken up in saturated sodium hydrogen carbonate-solution and extracted three times with dichloromethane. The organic layers were dried over magnesium sulfate and evaporated. Final purification was achieved by silicagel chromatography. Rt=1.93 min (Method B). Detected mass: 344.1 (M+H+).
