Versuchsvorschrift
A mixture of 1.14 g of 2,6-dichloro-4-(3,3-dichloro-2-propenyloxy)phenol, 1.20 g of 3-(4-chlorophenoxy)propyl bromide, 0.83 g of potassium carbonate and 20 ml of N,N-dimethylformamide was stirred at 80° C. for 6 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 1.01 g of 3,5-dichloro-1-(3,3-dichloro-2-propenyloxy)-4-(3-(4-chlorophenoxy)propyloxy)benzene (55% yield), nD25.0 1.5822.
