Reaction Steps
To a solution of 3-methoxy-2(1 h)-pyridone (1.00 g, 7.99 mmol, AstaTech, Inc) in DCM (26 mL) at 0° C. was slowly added bromine (0.819 mL, 15.98 mmol). After addition, the mixture was stirred at rt for 18 h. The mixture was then cooled to 0° C. and saturated aqueous NaHCO3 (4 mL) was slowly added. The mixture was then stirred at rt for 30 min. The organic layer was collected and the aqueous layer was extracted with EtOAc (1×20 mL). The combined organic layers were dried over MgSO4 and concentrated in vacuo. The residue was then dissolved in MeOH (20 mL) and silica gel was added. The mixture was concentrated and dried in vacuo. The solid mixture was purified by silica gel flash column chromatography (solid loading, 0%-100% EtOAc/hexane) to give the title compound as a tan solid. MS (ESI, positive ion) m/z: 204,206 (M+H).
