5-Bromobenzo[d]oxazole, cas is 132244-31-6, it is a common heterocyclic compound, the benzoxazole compound, its synthesis route is as follows.,132244-31-6
A flasked charged with 5-bromo-benzooxazole (200.0 mg, 1.01 mmol), bis(pinacolato)diboron (256.0 mg, 1.51 mmol), KOAc (198.0 mg, 2.02 mmol) and Pd(dppf)Cl2 (37 mg, 0.05 mmol) in dioxane (10 mL) was degassed and filled with N2. The reaction mixture was heated at 100 C for 16 hrs. Solvent was removed and the residue was purified by flash column chromatography (EA/PE = 1 :4) to give l,3-benzoxazole-5-boronic acid pinacol ester (120 mg, 48.6 %) as a yellow solid. MS: m/z 246.4 (M+H+).
With the rapid development of chemical substances, we look forward to future research findings about 5-Bromobenzo[d]oxazole
