GENERAL METHOD: 2-bromo-6-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. After the reaction was completed, water (400 mL) was added to dilute and the mixture was extracted with hexane. The organic phase was separated, washed with water, dried over anhydrous sodium sulfate, filtered through a short column of silica gel and the filtrate was concentrated under reduced pressure to give 2-bromo-6-fluoroanisole.
