2-Bromo-6-methoxypyridine Use and Manufacturing
2-Bromo-6-methoxypyridine; In an argon atmosphere, sodium methoxide (1.82 g) was added to 2, 6-dibromopyridine (8.0 g) in toluene (120 mL), followed by stirring at 120°C for 13 hours. Subsequently, sodium methoxide (0.728 g) was added to the mixture, followed by stirring at 120°C for 6 hours. The mixture was cooled in air. The reaction mixture was partitioned between water and ethyl acetate. The organic layer was dried over sodium sulfate anhydrate, followed by filtration. The solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (hexane - ethyl acetate), to thereby give the title compound in an oily substance (5.64 g, 89percent).1H-NMR(400MHz, CDCl3)δ: 3.93(3H, s), 6.68(1H, d, J=8.0Hz), 7.05(1H, d, J=7.2Hz), 7.39-7.42(1H, m).Step A 2-bromo-6-methoxypyridine (3a)
