Versuchsvorschrift

A mixture of 0.61 g of 3,5-dichloro-4-(4-bromobutyloxy)-1-(3,3-dichloro-2-propenyloxy) benzene, 0.19 g of 4-chlorophenol, 0.22 g of potassium carbonate and 20 ml of N,N-dimethylformamide was stirred at room temperature. After 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 0.54 g of 3,5-dichloro-4-(4-(4-chlorophenoxy) butyloxy)-1-(3,3-dichloro-2-propenyloxy)benzene (59% yield), m.p. 54.5° C.
