3-BROMO-5-CHLORO-2-METHOXY-PYRIDINE Use and Manufacturing

PREPARATION 13; (5-Chloro-2-methoxypyridin-3-yl)boronic acid a) 3-Bromo-5-chloro-2-methoxypyridineA solution of bromine (1.5 mL, 29.28 mmol) in glacial acetic acid (7 mL) was slowly added to a mixture of 5-chloro-2-methoxypyridine (2.1 g, 14.63 mmol) and sodium acetate (1.2 g, 14.63 mmol) in glacial acetic acid (7 mL) and the resulting mixture was stirred at 80 °C for 6 hours. The reaction was allowed to cool down to ambient temperature and then diethyl ether and water were added. The organic layer was separated, washed with a 1N aqueous solution of sodium hydroxide and a 4percent aqueous solution of sodium bisulphite, dried over magnesium sulphate and the solvent removed under reduced pressure. The residue was purified by flash chromatography (100percent hexanes) to give the title compound (2.1 g, 64percent) as a white solid.PREPARATION 13; (5-Chloro-2-methoxypyridin-3-yl)boronic acid a) 3-Bromo-5-chloro-2-methoxypyridine A solution of bromine (1.5 mL, 29.28 mmol) in glacial acetic acid (7 mL) was slowly added to a mixture of 5-chloro-2-methoxypyridine (2.1 g, 14.63 mmol) and sodium acetate (1.2 g, 14.63 mmol) in glacial acetic acid (7 mL) and the resulting mixture was stirred at 80 C for 6 hours.
