Procedure

A mixture of 0.5 g of 3,5-dichloro-4-[3-(5-trifluoromethylpyridin-2-yloxy)propyloxy]phenol, 0.25 g of 1,1,3-trichloropropene, 0.2 g of potassium carbonate and 3 ml of N,N-dimethylformamide was stirred at room temperature overnight. The reaction mixture was subjected to silica gel chromatography, which afforded 0.3 g of 3,5-di-chloro-1-(3,3-dichloro-2-propenyloxy)-4-[3-(5-trifluoromethylpyridin-2-yloxy)propyloxy]benzene (47% yield), nD20.5 1.5377.
