Reaction Steps

A suspension of 4-bromo-2-ethoxyphenol (8 g), bromoethylethyl ether (5 ml), sodium iodide (5.5 g) and potassium carbonate (10.2 g) in DMF (10 ml) was stirred under nitrogen atmosphere at 90° C. overnight. The solvent was evaporated, and to the residue was added water. The mixture was extracted with ethyl acetate. The organic layer was washed with water and saturated brine, and dried with anhydrous magnesium sulfate. The solvent was evaporated, and the residue was distilled under reduced pressure to give 1-bromo-3-ethoxy-4-(2-ethoxyethoxy)benzene (8.1 g) as yellow oil.
