実験手順
2-Bromo-5-fluoropyridine (15 g, 85.6 mmol), trifluoroacetic acid (70 mL, 908 mmol) and hydrogen peroxide (35% in water) (9 mL, 105 mmol) were stirred overnight at 70° C. The mixture was poured into water and extracted with dichloromethane. The organic layers were washed with NaHCO3 (aq), dried over MgSO4 and the solvent was removed i.vac.
