Simple exploration of Oxazolo[4,5-b]pyridin-2(3H)-one

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,60832-72-6, its application will become more common.

Adding a certain compound to certain chemical reactions, such as: 60832-72-6, Oxazolo[4,5-b]pyridin-2(3H)-one, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, 60832-72-6, blongs to pyridine-derivatives compound. Recommanded Product: 60832-72-6

To a stirred suspension of [1 ,3]oxazolo[4,5-o]pyridin-2(3H)-one (1-51) (34 g, 0.25 mol) in MeCN (0.35 L) was added NBS (47.6 g, 0.275 mol) in a portionwise manner at 0 C. After addition, the reaction mixture was stirred at room temperature for 3 h. TLC (EtOAc/hexane = 1 :1) indicated the reaction was complete. The precipitate was filtered, washed with cold MeCN (150 ml_) and dried under vacuum to yleld 6-bromo[1 ,3]oxazolo[4,5-o]pyridin-2(3H)-one (I-52) (45 g, 84%) as a yellow solid, which was used directly in the next step.

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,60832-72-6, its application will become more common.
