Thionyl Chloride → 2-(Chloromethyl)-4-(3-methoxypropoxy)-3-methylpyridine

Participants

Reaction Steps

2-Hydroxymethyl-4-(3-methoxypropoxy)-3-methylpyridine (5.0 g (23.7 mmol)) was dissolved in ethyl acetate (40 ml), and thionyl chloride (4.23 g (35.6 mmol)) was added dropwise into the solution in a temperature that did not exceed 25° C. Stirring was carried out at room temperature, and then after it had been confirmed by TLC that the starting material had disappeared, vacuum concentration was carried out, thus obtaining 2-chloromethyl-4-(3-methoxypropoxy)-3-methylpyridine (6.14 g (yield: 97.4%)).
