To 20 ml of toluene was added 0.60 g of sodium hydride (60% in oil) and the mixture was refluxed, and a solution of 2.0 g of 2-(4-fluorophenyl)-2-methylbutyl alcohol in 10 ml of 40% DMF/toluene was added dropwise to the mixture over a period of 20 minutes. The mixture was stirred for 10 minutes and a solution of 4.0 g of 3-(4-bromophenoxy)benzyl bromide in 10 ml of toluene was added dropwise to the mixture over a period of 10 minutes. The mixture was further heated and refluxed for 1 hour and cooled to room temperature, and poured into water. The toluene 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 100 g of silica gel (1:1 mixed solvent of toluene and hexane was used as eluent) to give 3.7 g of the desired ether (the yield was 76% of the theoretical yield).
