Reaction Steps

To 5 ml of dimethylformamide were added 0.5 g of 4-(2,2,2-trifluoro-1-hydroxyethyl)pyridine-2-carbonitrile, 0.45 g of potassium carbonate and 0.39 g of 3-bromo-1-propene, and the mixture was stirred at room temperature for 20 hours. Thereafter, an aqueous saturated ammonium chloride solution was added to the reaction solution, the resultant solution was extracted with ethyl acetate, and the organic layers were combined, dried with anhydrous magnesium sulfate, and concentrated. The residue was subjected to silica gel column chromatography to obtain 0.17 g of 4-[2,2,2-trifluoro-1-(2-propenyloxy)ethyl]pyridine-2-carbonitrile.
