Hexanol (1.5 mL, 12 mmol) was added to a pyridine (10 mL) solution dissolved with 60% sodium hydride containing mineral oil (0.56 g, 14 mmol) at 0° C., and the resultant solution was stirred for 1 hour at room temperature. After the solution was cooled to −20° C., {4-(pentafluorophenyl)-2,3,5,6-tetrafluorophenyl}bis(triflyl)methane (1.2 g, 2 mmol) was added. The reaction solution was stirred at −20° C. for 5 hours. After the reaction, the solution was acidified with 4 M hydrochloric acid water, and was extracted with diethylether. After drying with magnesium sulfate, the solution was filtrated, and the solvent was removed under reduced pressure. The crude product was purified by sublimation (0.2 to 0.3 torr, 80° C.), and {4-(4-hexanoxy-2,3,5,6-tetrafluorophenyl)-2,3,5,6-tetrafluorophenyl}bis(triflyl)methane was obtained at 94% yield (1.27 g, 1.88 mmol).
