Procedure
To a mixture of 0.56 g of 3,5-dichloro-4-(3,5-bistrifiuoromethyl-2-pyridyloxy)phenol, 0.22 g of potassium carbonate and 20 ml of N,N-dimethylformamide, a solution prepared by dissolving 0.23 g of 1,1,3-trichloro-1-propene in 5 ml of N,N-dimethylformamide was added dropwise at room temperature with stirring. After stirring at room temperature for 7 hours, the reaction solution was poured into ice-water, and extracted twice with 50 ml of diethyl ether. Then, the ether layers were combined, washed with water, dried over anhydrous magnesium sulfate and then concentrated to give a crude product. This crude product was subjected to silica gel chromatography to give 0.50 g of 3,5-dichloro-4-(3,5-bistrifiuoromethyl-2-pyridyloxy)-2-(3,3-dichloro-2-propenyloxy)benzene, yield 70%; m.p., 78.2° C.
