Procedure

To a solution of 4-(5-benzyloxy-6-chloro-3-cyanoindol-1-yl)benzoic acid ethyl ester (0.310 g) in dichloromethane (7 mL) was added boron tribromide (1 mol/L dichloromethane solution) (0.860 mL) under ice cooling, and this mixture was stirred at the same temperature for 1 hour. To this reaction mixture was added water, this mixture was extracted with ethyl acetate. This organic layer was washed with brine, dried over anhydrous magnesium sulfate and filtered. This filtrate was removed under reduced pressure. The residue was washed with diethyl ether to give the title compound (0.181 g).
