3-Bromo-5-bromomethyl-2-methoxy-pyridine (6.03 g, 21.5 mmol), N-bromosuccinimide (4.09 g, 23.0 mmol), and azobisisobutyronitrile (one scoop) were combined in benzene (40 mL) and stirred at 80° C. for 4 hours. After cooling, the mixture was diluted with H2O and extracted with EtOAc. The combined organic layers were dried over MgSO4, filtered, and concentrated to give 3-Bromo-5-dibromomethyl-2-methoxy-pyridine.
