反応手順
1.39 g of 4-chloromethyl-2-phenylthiazole was dissolved in 10 ml of acetonitrile, and 0.65 g of potassium cyanide and 0.05 g of dibenzo-18-crown-6-ether were added thereto at room temperature, and then heated under reflux for 10 hours. After the temperature was returned to room temperature, ethyl acetate was added the resulting mixture, and the insoluble solid was removed through filtration. The resulting ethyl acetate solution was washed with saturated saline and water, and dried over sodium sulfate, and the solvent was distilled off under reduced pressure. The residual product was purified through silica gel column chromatography to obtain 0.98 g of 4-cyanomethyl-2-phenylthiazole from the fraction eluted with chloroform.
