Procedure

2-Hydroxymethyl-4-(3-methoxypropoxy)-3-methylpyridine (5.0 g (23.7 mmol)) was dissolved in dichloromethane (40 ml), and thionyl chloride (4.23 g (35.6 mmol)) was added dropwise thereto so that the temperature did not exceed 25° C. Following stirring at room temperature, disappearance of the raw materials was confirmed by TLC, and 2-chloromethyl-4-(3-methoxypropoxy)-3-methylpyridine (6.23 g) was obtained by concentrating under a reduced pressure (yield: 99.0%).
