Procedure
To a solution of 3-bromo-4-fluorophenol (2.18 g, 11.4 mmol) in DMF (15 mL) was added potassium carbonate (3.15 g, 22.8 mmol) portion wise at room temperature. The mixture was stirred at room temperature for 10 minutes then 4-methoxybenzyl chloride (1.55 mL, 11.4 mmol) was added drop wise. On completion of the addition the reaction was heated at 60° C. under nitrogen for 15 hours. The cooled reaction mixture was quenched with water (50 mL) and extracted with EtOAc (3×50 mL). The combined extracts were washed with 1M aqueous NaOH solution (50 mL) and brine (50 mL), then dried over anhydrous MgSO4, filtered and concentrated in vacuo to afford the crude title compound as an off-white solid in quantitative yield, 3.62 g.
