Reaction Steps

1-Ethyl-6-(hydroxymethyl)-2-oxo-1,2-dihydropyridine (1.51 g, 9.86 mmol) obtained in Step 2 and triethylamine (2.06 mL, 14.8 mmol) were dissolved in dichloromethane (40 mL), and at 0° C., methanesulfonyl chloride (0.920 mL, 11.8 mmol) was added dropwise thereto, followed by stirring at 0° C. for 30 minutes. Water was added to the reaction mixture, followed by extraction with chloroform. The organic layer was washed with a saturated aqueous solution of sodium chloride and dried over anhydrous magnesium sulfate, and then the solvent was distilled away under reduced pressure to afford 1-ethyl-6-(methanesulfonyloxymethyl)-2-oxo-1,2-dihydropyridine (2.29 g, 100%).
