Procedure
To a mixture of 4-bromo-2-fluorophenol (10.07 g) and potassium carbonate (9.5 g) in DMF (100 ml) was added at room temperature 2-bromoethylethyl ether (6.0 ml), and the mixture was stirred for 18 hours. To the mixture was added 2-bromoethylethyl ether (1.2 ml), and the mixture was stirred at 55° C. for 5 hours. To the mixture was added water, and the mixture was extracted with ethyl acetate. The organic layer was washed with water (thrice) and saturated brine (once), and dried with magnesium sulfate. The solvent was evaporated under reduced pressure to give pale yellow oil of 4-bromo-1-(2-ethoxyethoxy)-2-fluorobenzene (13.79 g).
