To a mixture of 2-bromo-5-fluorophenol (10 g, 50.8 mmol) and iodomethane (11.2 g, 78.7 mmol) in dimethylformamide (100 mL) was added potassium carbonate (10.9 g, 79 mmol) and the mixture stirred at room temperature for 3 hrs. The mixture was diluted with water (100 mL) and extracted with ether (50 mL×3). The combined extracts were washed with brine, dried over anhydrous magnesium sulfate, and concentrated in vacuo to obtain 11.3 g of 1-bromo-4-fluoro-2-methoxybenzene as an amber colored oil.
