Versuchsvorschrift

First, 0.35 g of 1-(3-bromopropyloxy)-4-trifluoromethylbenzene (prepared in the same manner as described above for 1-(3-bromopropyloxy)-4-trifluoromethoxybenzene) and 0.2 g of potassium carbonate were dissolved in 100 ml of N,N-dimethylformamide, to which 0.3 g of 2-chloro-6-methyl-4-(3,3-dichloro-2-propenyloxy)phenol was added, and the mixture was stirred at room temperature for 24 hours. The reaction mixture was mixed with 200 ml of diethyl ether, 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 0.50 g of 3-chloro-4-[3-(4-trifluoromethylphenoxy) propyloxy]-5-methyl-1-(3,3-dichloro-2-propenyloxy)benzene (94% yield), nD23.0 1.5330.
