5.0 g of (5-methyl-2-phenyl-1,2,3-triazol4-yl)methan-1-ol was dissolved in 35 ml of dichloromethane, then 6.3 g of thionyl chloride was added dropwise thereto under cooling with ice. After stirring for 1 hour at room temperature, 100 ml of water was added. The resulting solution was made alkaline with 8 g of potassium carbonate, then extracted with chloroform. The organic phase was washed with water and a saturated salt solution, then dried over anhydrous sodium sulfate. After the solvent was distilled off, 5.2 g of the aimed compound was obtained.
