Procedure

Boron tribromide (2M dichloromethane solution, 1.0 ml) was added to a dichloromethane (50 ml) solution of 2-[4-(4-benzo[b]thiophen-4-yl-piperazin-1-yl)butyl]-7-methoxy-2H-isoquinolin-1-one (0.16 g) while being stirred under ice-cooling and stirred at room temperature for 3 days. Water was added to the reaction solution, which was then stirred at room temperature for 0.5 hour. Precipitated crystals were separated by filtration, recrystallized from ethyl acetate and thereby 2-[4-(4-benzo[b]thiophen-4-yl-piperazin-1-yl)butyl]-7-hydroxy-2H-isoquinolin-1-one hydrobromide (0.13 g) was obtained in the form of a white powder.
