Reaction Steps
450 mg of the 2-hydroxymethyl-4-(3-methoxypropoxy)-3-methylpyridine prepared above was dissolved in 20 ml of dichloromethane to obtain a solution. 760 mg of thionyl chloride was dropwise added to this solution at 0° C. The obtained mixture was stirred at a room temperature for 2 hours. After the completion of the reaction, the reaction mixture was distilled to remove the dichloromethane and the thionyl chloride. A saturated aqueous solution of sodium hydrogencarbonate was added to the obtained residue. The obtained mixture was extracted with chloroform. The obtained chloroform layer was concentrated to obtain 470 mg of 2-chloromethyl-4-(3-methoxypropoxy)-3-methylpyridine as a brown crystal.
