Procedure

2-Chloro-3-pyridinol (1.3 g), 1.88 g of p-methoxybenzyl chloride, and 1.4 g of potassium carbonate were added to 10 ml of dimethylformamide, followed by stirring at 60° C. for 17 hours. The reaction mixture was diluted with ethyl acetate and washed successively with water and a saturated sodium chloride aqueous solution. After drying, the solvent was removed by evaporation, and the residue was subjected to silica gel column chromatography using a 1:4 (by volume) mixture of ethyl acetate and hexane as a developing solution. The fraction containing the desired compound was concentrated to afford 2.18 g of the title compound.
