A reaction vessel was charged with 1.54 g of 3,5-dichloro-4-hydroxyphenyl benzoate, 0.83 g of potassium carbonate, 1.53 g of 4-fluoro-3-phenoxybenzyl bromide, and 10 ml of N,N-dimethylformamide, followed by stirring at room temperature for 5 hours. The reaction mixture was poured into water, and extracted twice with 50 m of diethyl ether. The combined ether layer was washed with water, dried with anhydrous magnesium sulfate, and concentrated to obtain a crude product. The crude product was subjected to silica gel chromatography, which afforded 2.32 g of 3,5-dichloro-4-(4-fluoro-3-phenoxybenzyloxy)phenyl benzoate (88% yield).
