Synthesis

884495-39-0
General procedure for the synthesis of 3-amino-5-bromo-2-methoxypyridine from 5-bromo-2-methoxy-3-nitropyridine: To a solution of 5-bromo-2-methoxy-3-nitropyridine (19.0 g, 82 mmol) in ethyl acetate (300 mL) was added tin (II) chloride dihydrate (74 g, 328 mmol). The reaction mixture was stirred and refluxed for 3 hours (note: an exothermic phenomenon occurs at the beginning of the reaction, which gradually subsides after about 10 minutes, at which time the heating bath can be temporarily removed). After completion of the reaction, the reaction mixture was cooled to room temperature and concentrated under reduced pressure to a light yellow slurry. The slurry was poured into water (300 mL), 6 N sodium hydroxide solution (300 mL), ice (300 g), and dichloromethane (300 mL) were added, and stirred for 2 hours until most of the solids were dissolved. A small amount of insoluble material was removed by filtration, the organic phase was separated, dried over anhydrous sodium sulfate, filtered and evaporated to dryness. The residual brown oil was solidified by grinding with hexane, filtered and dried under vacuum to give the target product 3-amino-5-bromo-2-methoxypyridine (13.40 g, 81% yield) as a light green solid. Mass spectrum (electrospray ionization) m/e: 202.8 [M+H]+.
