Reaction Steps

4.60 g (0.2 mol) of metallic sodium was dissolved in 80 ml of ethylene glycol under cooling with ice to obtain a solution. This solution was stirred in a nitrogen atmosphere at 100° C. for one hour, followed by the addition of 15.76 g (0.1 mol) of 4-chloro-2,3-dimethylpyridine N-oxide at a room temperature. The obtained mixture was stirred at 120° C. for 2 hours. After the completion of the reaction, the reaction mixture was distilled to dryness to remove the ethylene glycol. The obtained residue was purified by silica gel column chromatography (solvent: chloroform/methanol=19:1) to obtain 13.28 g of 4-(2-hydroxyethoxy)-2,3-dimethylpyridine N-oxide as a white crystal.
