As a common heterocyclic compound, it belongs to benzoxazole compound, name is Benzo[d]oxazol-2-amine, and cas is 4570-41-6, its synthesis route is as follows.
2-Bromopyridine (1) (lOg, 6.3mmol), benzo[d]oxazol-2-amine (2) (0.871g,6.4mmol), Xantphos (0.366g, 0.63mmol), and Cs2003 (3.09g, 9.4mmol) were combined in dry 1,4-dioxane (l5mL). The reaction mixture was degassed with N2(g) and placed under vacuum for 10mm. Pd2(dba)3 (0.289g, 0.31 mmol) was then added and the resulting reaction mixture was heated at 90°C for 30h. It wasthen poured onto demineralized water (200mL), and extracted with EtOAc (3 x lOOmL). The organic phases were combined, dried over Na2SO4, filtered and subsequently evaporated under vacuum. The resulting residue was purified by flash chromatography, eluting with EtOAc/Hexane (1:1) to provide N-(pyridin-2- yl)benzo[d]oxazol-2-amine (3) as a yellow solid (0.8g, 60percent).LCMS (ES): Found 212.1 [MH]+.
4570-41-6, In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles.,4570-41-6 ,Benzo[d]oxazol-2-amine, other downstream synthetic routes, hurry up and to see
