실험 절차
To an ice-cold solution of 4-(4-fluorobenzyloxy)pyridine-2(1H)-one (3.1 g, 14 mmol) in AcOH (26 mL) was added a solution of bromine (0.79 mL, 15 mmol) in AcOH (51 mL), and the reaction mixture was stirred at room temperature for 2 h. The solvent was removed under reduced pressure, and purification by flash column chromatography (silica, 1:1 Et2O/hexanes) to afford 3-bromo-4-(4-fluorobenzyloxy)-1H-pyridin-2-one as an orange solid (0.78 g, 48%): MS APCI m/z 298 [M+H]+.
