Reaction Steps
Boron tribromide (11.8 g) was slowly added dropwise to dichloromethane (41 mL) cooled to −78° C., and then Compound (e) (6.47 g) dissolved in dichloromethane (60 mL) was slowly added dropwise at the same temperature and the mixture was stirred at room temperature for 2 hours. The reaction mixture was then poured into ice water and the aqueous layer was extracted with ether. The organic layers were combined, washed with saturated aqueous sodium chloride, and dried over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure to obtain 3.53 g of Compound (g).
