To a solution of methyl 6-chloro-5-hydroxynicotinate (10.5 g) in DMF (80 mL) was added 60% sodium hydride (2.80 g) at 0° C., and the mixture was stirred at 0° C. for 0.5 hr. Benzyl bromide (10.5 g) was added, and the mixture was stirred at room temperature for 20 hr. The reaction mixture was poured into water, and the precipitate was collected by filtration. The crude crystals were purified by silica gel column chromatography (petroleum ether/THF) to give the title compound (6.00 g) as a white solid.
