Procedure
12 g of 2-benzyl-3-hydroxy-6-iodopyridine was dissolved in 50 ml of tetrahydrofuran, followed by adding 3.8 ml of chloromethyl methyl ether. 2 g of 60% oily sodium hydride was added little by little thereto to under stirring under ice-cooling. After adding sodium hydride, the cooling medium was removed and the mixture was stirred at room temperature for 2.5 hours. Then, ice water was added thereto little by little under cooling, followed by extracting with ethyl acetate. The organic phase was further washed brine, dried over anhydrous sodium sulfate and the solvent was removed. The residue was subjected to silica gel column chromatography using 15% ethyl acetate/hexane as an eluent for separation and purification, to give 13 g of the target compound.
