To a solution of 4-bromophenol (646, 5.0 g, 28.9 mmol) in dimethylformamide (15 mL) were added potassium carbonate (4.40 g, 31.8 mmol) and 1-bromo-2-methoxyethane (5.00 g, 36.0 mmol) under an atmosphere of nitrogen. The reaction mixture was stirred at ambient temperature overnight and concentrated under reduced pressure. The residue was slurried in ethyl acetate (50 mL) and filtered. The filtrate was washed with saturated sodium bicarbonate solution, dried over magnesium sulfate and filtered. Silica gel column chromatography (0-10% ethyl acetate in hexanes) gave the desired compound as a colorless oil (647, 3.2 g, 48%).
