Step AM2: 3-Bromo-5-bromomethyl-2-methoxy-pyridine To a solution of 3-bromo-2-methoxy-5-methyl-pyridine (Step AM3) (3.0 g, 14.7 mmol), was added NBS (3.1 g, 17.6 mmol) and AIBN (121 mg, 0.7 mmol) and the mixture was stirred at 80 C. for 1 h. H2O and CH2Cl2 were added and the phases were separated. The organic layer was dried (MgSO4), filtered and concentrated. The crude product was purified by silica gel column chromatography (heptane/EtOAc, 95:5?0:100). tR: 1.10 min (LC-MS 1).
