2-amino-5-bromopyridin-3-ol Chemical Properties,Uses,Production

Uses

2-Amino-5-bromo-3-hydroxypyridine is used as an organic chemical synthesis intermediate.

Synthesis

6-BROMO-3H-OXAZOLO[4,5-B]PYRIDIN-2-ONE

21594-52-5

2-amino-5-bromopyridin-3-ol

39903-01-0

General procedure for the synthesis of 3-hydroxy-2-amino-5-bromopyridine from 6-bromo-3H-oxazolo[4,5-b]pyridin-2-one: 6-bromo-3H-oxazolo[4,5-b]pyridin-2-one (21.5 g, 100 mmol) was suspended in 2N NaOH solution (250 mL, 500 mmol). The mixture was refluxed and reacted overnight until a clarified solution was formed. Upon completion of the reaction, the mixture was cooled to room temperature and subsequently neutralized with acid to a pH of about 7. During this process, the release of large amounts of CO2 gas as well as the formation of a precipitate was observed. The precipitate was collected by filtration, washed with water and dried under high vacuum to give the final 2-amino-5-bromopyridin-3-ol as an off-white solid (17.8 g, 98% yield).
