Reaction Steps
27.6 g of malononitrile was dissolved in 50 ml of N,N-dimethylformamide, 27.6 g of potassium carbonate was added, and the mixture was stirred at room temperature for 1 hour. Thereafter, a mixture of 17.7 g of 1-bromo-3,3,3-trifluoropropane and 20 ml of N,N-dimethylformamide was added thereto and the mixture was further stirred for 1 hour. Thereafter, the reaction mixture was poured to water and then extracted with diethyl ether. 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 11.3 g of 2-(3,3,3-trifluoropropyl)malononitrile.
