GENERAL METHOD: 2-Bromo-3-fluorophenol (0.1 mol) was dissolved in DMF (100 mL) and K2CO3 (0.1 mol) and iodomethane (0.1 mol) were added sequentially. The reaction mixture was stirred at room temperature for 24 hours. Upon completion of the reaction, water (400 mL) was added to dilute and the mixture was extracted with hexane. The organic phases were combined, washed with water, dried over anhydrous sodium sulfate, filtered through a silica plug and concentrated under reduced pressure to give 2-bromo-3-fluoroanisole.
