Reaction Steps

To a flask containing 6-aminopyridin-3-ol hydrobromide (2 g, 10.5 mmol) and ethyl-2-bromo-2-methylpropanate (2.04 g, 10.5 mmol) in anhydrous acetonitrile (25 ml) was added cesium carbonate (10.7 g, 33 mmol) and the material was stirred for 16 hours under argon atmosphere. Water (60 ml) and ethyl acetate (60 ml) were added and the material was shaken in a reparatory funnel. The organic phase was collected and the aqueous phase was back extracted with ethyl acetate (2×50 ml). The combined organic phases were dried over magnesium sulfate, filtered and concentrated in vacuo. to provide a golden brown solid (1.626 g)(M+H)+=225 m/e.
