Versuchsvorschrift
Under a nitrogen atmosphere, 0.50 g of 2-(4-fluorophenyl)-3,3,3-trifluoropropanol and 0.63 g of 3-phenoxybenzyl bromide was dissolved in 15 ml of dry diethyleneglycol dimethylether. Into the solution, 1.83 g of dry cesium fluoride was added at room temperature, and the reaction solution was stirred at room temperature for 48 hours. Thereafter, the reaction solution was poured into dilute HCl-ice water and extracted twice with diethyl ether. The ether layers were combined, washed with saturated sodium chloride solution and dried over anhydrous magnesium sulfate. The solvent was removed under a reduced pressure, and the residue was subjected to preparative thin-layer chromatography on silica gel to obtain αmg of the desired compound.
