Water → Tert-butyl 2-(3-pyridyloxy)acetate

Participants

Reaction Steps

To a suspension of 0.22 g of sodium hydride (60% oil dispersion, 5.5 mmol) in 2 mL of DMF was added dropwise a solution of 0.48 g of 3-hydroxypyridine (5.0 mmol) in 2 mL of DMF at room temperature, and the mixture was stirred for an hour. The resulting brown solution was ice-cooled, 0.81 mL of tert-butyl bromoacetate (5.5 mmol) was added, and the mixture was stirred under ice-cooling for an hour followed by stirring at room temperature for 2 hours. After addition of water, the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, dried and evaporated. The residue was purified by column-chromatography on silica gel (eluent: chloroform:ethyl acetate=5:1), to give 0.34 g of tert-butyl 3-pyridyloxyacetate (Yield: 32.5%) as a clear oil.
