Versuchsvorschrift

6.3 g (13 mmol) of 4-(2-(4-(4-ethoxymethylcyclohexyl) cyclohexyl) ethyl) trifluoromethylsulfonyloxybenzene, 4.2 g (17 mmol) of dihydroxy (3,5-difluoro-4-trifluoromethoxyphenyl) borane, 5% palladium on activated charcoal (1.0 g) and 5.7 g (54 mmol) of sodium carbonate were refluxed in toluene/alcohol/water (1/1/1 v/v, 80 ml) under a nitrogen atmosphere for 3 days. After cooling, the reaction solution was added with water (150 ml) and extracted twice with toluene (150 ml). An organic layer was dried over anhydrous magnesium sulfate, filtered and the solvent therein was distilled off under a reduced pressure. The residue thus obtained was purified by column chromatography (silica gel/heptane:toluene=5:1) and recrystallization (heptane-ethanol) to obtain colorless crystals of 4-(4-(2-(4-(4-ethoxymethylcyclohexyl)cyclohexyl)ethyl)phenyl)-2,6-difluorotrifluoromethoxybenzene.
