A reaction vessel was charged with 11.1 g of 3,5-dichloro-4-(3-bromopropoxy)-1-(3,3-dichloro-2-propenyloxy)benzene, 3.31 g of benzoic acid, 3.90 g of potassium carbonate and 50 ml of N,N-dimethylformamide. After stirring at room temperature for 24 hours, the reaction mixture was poured into water and extracted twice with 150 ml of diethyl ether. The ether layers were combined, and washed with water, dried over anhydrous magnesium chloride, and then concentrated to give a crude product. The crude product was subjected to silica gel chromatography, which afforded 11.6 g of 3,5-dichloro-4-(3-benzoyloxypropyloxy)-1-(3,3-dichloro-2-propenyloxy)benzene (95% yield).
