Electric Literature of 1026796-81-5, In the chemical reaction process,reaction time,type of solvent,can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product.An updated downstream synthesis route of 1026796-81-5 as follows.
To a solution of N-(4-bromopyridin-2-yl)acetamide (350 mg, 1.6 mmol) in DCM (20 mL) was added mCPBA (1.26 g, 7.3 mmol) at 0 C. The reaction mixture was allowed to stir at rt for 3 h. The reaction mixture was then diluted with water and saturated K2CO3 solution, and extracted with DCM. The organic solutions were combined, dried over Na2SO4, filtered and concentrated. The crude compound was purified by column chromatography to provide N-(4-bromo-1-oxidopyridin-2-yl)acetamide (340 mg, 90%). LCMS (FA): m/z=231.3 (M+H).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,1026796-81-5, its application will become more common.
