Procedure

5.3 g of 4-(2-benzyloxyethoxy)-2-hydroxymethyl-3-methylpyridine was dissolved in 60 ml of chloroform to obtain a solution. A solution of 5.8 g of thionyl chloride in 40 ml of chloroform was dropwise added to the above solution under cooling with ice. The obtained mixture was stirred at a room temperature for 7 hours and distilled under a reduced pressure to obtain a residue. 200 ml of a 2N aqueous solution of sodium carbonate was added to the residue. The obtained mixture was extracted with chloroform and the extract was dried over magnesium sulfate and distilled to remove the chloroform. 6.3 g of the title compound was obtained.
