Versuchsvorschrift

To a solution prepared by dissolving 0.44 g of 2-trifluoromethyl-4-(3-ethoxyphenoxy)phenol in 10 ml of N,N-dimethylfonnamide, 0.062 g of sodium hydride (60% oil-based) was added with stirring under ice cooling. After 10 minutes, a solution prepared by dissolving 0.24 g of 1,1,3-trichloro-1-propene in 5 ml of N,N-dimethylformamide was added dropwise under ice cooling. After stirring at room temperature for 10 hours, the reaction solution was poured into ice-water, and extracted twice with 50 ml of diethyl ether. Then, the ether layers were combined, washed with water, dried over anhydrous magnesium sulfate and concentrated to give a crude product. This crude product was subjected to silica gel chromatography to give 0.37 g of 2-trifluoromethyl-4-(3-ethoxyphenoxy)-1-(3,3-dichloro-2-propenyloxy)benzene, yield 62%; nD23.6 1.5369.
