Procedure

To a mixture of 0.40 g of 2,6-dichloro-4-(3,3-dichloro-2-propenyloxy)-phenol, 0.21 g of potassium carbonate and 20 ml of N,N-dimethylformamide was added dropwise a solution of 0.25 g of 6-chloro-3-(chloromethyl)pyridine dissolved in 5 ml of N,N-dimethylformamide, while stirring at room temperature. After stirring at room temperature for 7 hours, the reaction mixture was poured into ice-water, and extracted twice with 50 ml 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 0.44 g of 3,5-dichloro-4-(6-chloro-3-pyridylmethyloxy)-1-(3,3-dichloro-2-propenyloxy)benzene (77% yield), m.p. 93.3° C.
