Sulfuric Acid → Benzene, 1-(4-fluorophenoxy)-3-((2-(4-fluorophenyl)-2-methylbutoxy)methyl)-

Participants

Reaction Steps

To 20 ml of toluene were added 2 ml of concentrated sulfuric acid, 2.7 g of 3-(4-fluorophenoxy)benzyl alcohol and 2.3 g of 2-(4-fluorophenyl)-2-methylbutyl alcohol, and the mixture was refluxed for 6 hours (water formed by reaction was removed). The mixture was cooled to room temperature, and water was added to the mixture and the toluene layer was separated, washed with water, dried, 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 n-hexane was used as eluent) to give 2.2 g of the desired ether (the yield was 46% of the theoretical yield).
