As a common heterocyclic compound, it belongs to benzoxazole compound, name is 5-Bromobenzo[d]oxazole, and cas is 132244-31-6, its synthesis route is as follows.,132244-31-6
Benzoxazole (1.0 mmol), N,N-disubstituted formamide (15 mmol), TBAI (0.2 equiv/74 mg), TBHP (70% aqueous solution, 10 mmol/1.37 mL), and acetic acid (5.0 equiv) in 1,2-dichloroethane (3.0 mL) were added to a reaction vessel in air. The reaction mixture was heated in an oil bath at 90 C for 12 h. After completion of the reaction, the mixture was quenched by addition of a saturated solution of sodium disulfite (4.0 mL, for removal of excess TBHP) and a saturated solution of sodium hydrogen carbonate (4.0 mL). Then the mixture was extracted with ethyl acetate (3 ¡Á 15 mL), combined organic phases were dried over anhydrous Na2SO4 and the organic solvent was removed under vacuum. The crude residue was purified by chromatography on a silica gel column affording the desired product.
With the complex challenges of chemical substances, we look forward to future research findings about 132244-31-6,belong benzoxazole compound
