Reaction Steps
Under nitrogen atmosphere, to a solution of 2-bromo-3-hydroxypyridine (10.00 g) in DMF (100 ml) was added sodium hydride (60% oil, 2.5 g) at 0° C., and the mixture was stirred for 30 minutes. To the reaction mixture was added methyl iodide (4.0 ml), and the mixture was stirred at room temperature for 2 hours. To the reaction mixture was added water, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated sodium chloride solution, dried with magnesium sulfate and concentrated. Under reduced pressure, the residue was separated and purified with column chromatography (ethyl acetate/hexane=1:2) to give 2-bromo-3-methoxypyridine (9.24 g) as colorless crystals.
