The above (3-chloro-4-methoxy-5-methylpyridin-2-yl)methanol (530 mg) was dissolved in 20 ml of chloroform, and thionyl chloride (1.03 ml) was then added dropwise to the solution under cooling on ice. The resulting mixture was stirred at room temperature for 3 hours. Thereafter, the reaction solution was concentrated, and it was then washed with a mixed solvent of ether-hexane, so as to obtain the title compound (410 mg) as a solid.
