A solution of pyridin-2-ol (1 g), tert-butyl bromoacetate (2.33 mL) and cesium carbonate (6.85 g) in DMF (20 mL) was stirred at 60° C. overnight. The reaction mixture was poured into water, and the mixture was partitioned twice with ethyl acetate. The organic layers were combined, and the mixture was washed with brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (0.18 g).
