Dimethyl Sulfoxide → HCID 86612542, compound

Participants

Reaction Steps

3.2 g of 2-(3,3,3-trifluoropropyl)malononitrile, 7.0 g of dibromomethane and 5.5 g of potassium carbonate were added to 40 ml of dimethyl sulfoxide, and the mixture was stirred at room temperature for 18 hours. 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 sodium sulfate and then concentrated under reduced pressure. The residue was subjected to silica gel column chromatography to obtain 3.4 g of 2-bromomethyl-2-(3,3,3-trifluoropropyl)malononitrile (hereinafter, referred to as the present compound (52)).
