Sodium Bicarbonate → 7-Chloro-2-(4-methoxy-benzyl)-6-(4-oxo-cyclohexyloxy)-2H-isoquinolin-1-one

Participants

Reaction Steps

1.00 g (2.19 mmol) of 7-chloro-6-(1,4-dioxa-spiro[4.5]dec-8-yloxy)-2-(4-methoxy-benzyl)-2H-isoquinolin-1-one (65) were stirred in 9 ml of 6 N HCl/acetone (1:2) at room temperature. After 2 h the reaction mixture was poured on saturated sodium bicarbonate solution and extracted with dichloromethane. The organic layer was dried with magnesium sulfate and evaporated. The crude product was purified by silica gel chromatography to give 630 mg of the title compound. Rt=1.81 min (Method B). Detected mass: 412.2 (M+H+).
