A reaction vessel was charged with 0.35 g of 3,5-diethyl-4-(4-(3,3-dichloro-2-propenyloxy)butyloxy)phenol, 0.16 g of 1,1,3-trichloro-1-propene, 0.15 g of potassium carbonate and 10 ml of N,N-dimethylformamide. After stirring at room temperature for 24 hours, the reaction mixture was poured into water and extracted twice with 50 ml of diethyl ether. The diethyl ether layers were combined, washed with water, dried over magnesium sulfate and then concentrated. The residue was subjected to silica gel chromatography, which afforded 0.33 g of 3,5-diethyl-1-(3,3-dichloro-2-propenyloxy)-4-(4-(3,3-dichloro-2-propenyloxy)butyloxy)benzene (yield, 72%), nD24.4 1.5311.
