Reaction Steps

To a solution of ethyl 3-(2-fluoro-5-methoxyphenyl)propanoate (100 mg) in dichloromethane (3.0 mL) was added dropwise a 1.0 M solution of boron tribromide in dichloromethane (0.15 mL) at −15° C., and the mixture was stirred at −15° C. for 5 hr. Water (20 ml) was added dropwise to the reaction mixture, and the mixture was extracted with dichloromethane. The extract was washed with saturated brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure to give the title compound (60 mg) as a colorless oil. This compound was used for the next step without further purification.
