Reaction Steps
A mixture of 3-bromopyridin-2-ol (1.0 g, 5.75 mmol) in DMF (6 mL) was treated with cesium carbonate (1.87 g, 5.75 mmol) and ethyl iodide (1.38 mL, 17.2 mmol). The mixture was heated at 80° C. for 4 hours. The solvent was concentrated and the residue taken in EtOAc, washed with brine, dried (phase separator silicone treated filter paper), concentrated and purified on silica gel (1:2 hexane/ether) to provide 3-bromo-1-ethylpyridin-2(1H)-one (0.905 g, 78% yield) as a yellow oil.
