To a solution of 1.7 g of 4,4,4-Trifluoro-2-butenyl p-toluenesulfonate and 1.2 g of (3,3,3-trifluoropropylsulfonyl)acetonitrile in 30 ml of tetrahydrofuran, 0.2 g of sodium hydride (60% in oil) was added at room temperature, and stirred at the same temperature for 1 day. To the reaction mixture, 10% hydrochloric acid was added, followed by extraction with ethyl acetate. The organic layer was washed with a saturated sodium chloride aqueous solution, dried over anhydrous magnesium sulfate, and then concentrated under reduced pressure. The obtained residue was subjected to silica gel chromatography to obtain 0.95 g of 6,6,6-trifluoro-2-(3,3,3-trifluoropropylsulfonyl)-4-hexenenitrile (hereinafter referred to as the present compound (19)).
