Versuchsvorschrift

2.0 g of 2-(4-difluoromethoxyphenyl)-2-methylpropyl alcohol, 2.0 g of m-phenoxybenzyl chloride, 20 g of 50% NaOH and 0.3 g of triethylbenzyl ammonium bromide were stirred at 50° C. for 2 hours. Then, H2O and benzene were added to the reaction mixture, and the mixture was sufficiently shaken and the benzene layer was separated, washed with water, dried over Na2SO4, and evaporated under reduced pressure, and the obtained crude ether was purified by column chromatography on 130 g of silica gel (2:3 mixed solvent of toluene and hexane was used as eluent) to give 3.0 g of the desired ether (the yield was 81% of the theoretical yield).
