실험 절차

1.2 g of 2-(2,2,3,4,4,4-hexafluorobutyl)malononitrile and 1.5 g of 2-chloro-1,4-dibromo-1,1,2-trifluorobutane were dissolved in 10 ml of dimethyl sulfoxide, 0.7 g of potassium carbonate was added, and the mixture was stirred at room temperature for 5 hours. Thereafter, dilute hydrochloric acid was added to the reaction mixture, followed by extraction with ethyl acetate. The organic layer was washed successively with water and aqueous saturated sodium chloride, dried over anhydrous magnesium sulfate, and then concentrated under reduced pressure. The residue was subjected to silica gel column chromatography to obtain 0.14 g of 2-(4-bromo-3-chloro-3,4,4-trifluorobutyl)-2-(2,2,3,4,4,4-hexafluorobutyl)malononitrile (hereinafter, referred to as the present compound (46)).
