Procedure
To a solution of 2-bromo-3-pyridinol (5 g) in THF (100 ml) at 0° was added sodium hydride (1 g, 80% suspension in oil). The mixture was stirred under nitrogen for 30 min and methyl bromoacetate (3.26 ml) was added dropwise. The mixture was then heated under reflux for 2 h, poured into water (300 ml) and extracted with ethyl acetate (2×250 ml). The combined organic extracts were dried and concentrated to give a solid which was triturated with ether to give the title compound as a white solid (4.5 g), m.p. 63°-64° C.
