Sodium hydride → 6-(4-Allyl-4-amino-cyclohexyl oxy)-7-chloro-2-(4-methoxy-benzyl)-2H-isoquinolin-1-one

Participants

Reaction Steps

155 mg (3.86 mmol) of sodium hydride (60%) were suspended in 3 mL of dimethyl acetamide and 220 mg (1.42 mmol) of 4-allyl-4-amino-cyclohexanol (16), dissolved in 1 mL of dimethyl acetamide, were added dropwise. After 1 h, 409 mg (1.29 mmol) of 2-(4-methoxy-benzyl)-6-fluoro-7-chloro-2H-isoquinolin-1-one (10), dissolved in another 2 mL of dimethyl acetamide, were added. The reaction mixture was stirred at room temperature until the reaction was complete. The mixture was quenched by dropwise addition of water, extracted with a mixture of dichloromethane and 2-propanol (3:1) and the combined organic layers were evaporated. Water was added and the crude product was subjected to lyophilization to remove remainders of dimethyl acetamide. The obtained crude product was purified by silica gel chromatography to yield 148 mg of the title compound (17) as diastereomeric mixture. Rt=1.35 min, 1.40 min (Method B). Detected mass: 453.3 (M+H+).
