Procedure

Into a vessel having an inner volume of 30 ml which was equipped with a stirring apparatus, a thermometer and a reflux condenser, 0.460 g (1.00 mmol) of 4-[(4-bromo-2,6-difluorophenyl)difluoromethoxy]pentafluorosulfanylbenzene, 0.411 g (1.15 mmol) of 4-(4-n-pentylcyclohexyl)-phenylboronic acid pinacol ester, 0.070 g (0.061 mmol) of tetrakis-(triphenylphosphine)palladium, 0.425 g (2.02 mmol) of tripotassium phosphate in the powder form and 5 ml of 1,4-dioxane were placed, and the reaction was allowed to proceed at 100° C. for 12 hours with stirring. After the reaction was completed, the reaction mixture was filtered, and the filtrate was concentrated under a reduced pressure. Then, the resulting residue was purified by the flush column chromatography (eluent: hexane), and 0.36 g (isolated yield: 59%) of 4-{[3,5-difluoro-4′-(4-n-pentylcyclohexyl)-biphenyl-4-yl]difluoromethoxy}pentafluorosulfanylbenzene was obtained as a white solid. The reaction scheme is shown in the following:
