A 5.0 g amount of tetrafluoroisophthalonitrile and 2.18 g of potassium fluoride were dissolved in 25 ml of acetonitrile, and 3.83 g of cyclohexanol was then dropwise added to the mixture. After the dropwise addition, the mixture was stirred at room temperature for 24 hours. The reaction mixture was filtered, the filtrate was concentrated in vacuo, and the concentrated liquid was poured to 50 ml of water. The resultant mixture was extracted with carbon tetrachloride. After washing with water, the extract was dried with anhydrous magnesium sulfate and the solvent was then distilled off. Thus, 6.2 g (88% yield) of the desired compound No. 47 was obtained.
