As a common heterocyclic compound, it belongs to benzoxazole compound, name is 6-Bromobenzo[d]oxazol-2(3H)-one, and cas is 19932-85-5, its synthesis route is as follows.,19932-85-5
Intermediate 13: 2-oxo-2,3-dihydrobenzo[d]oxazole-6-carbonitrile To a solution of 6-bromo benzoxazolinone (2 g, 9.4 mmol) in DMF (20 mL) was added CuCN (16.79 g, 188 mmol), and the reaction was stirred at 175 C. for 6 h. The reaction progress was monitored by TLC (100% EtOAc). The reaction was diluted with EtOAc (10 mL) and filtered through Celite brand filter agent. The organic layer was concentrated and purified by column chromatography (silica gel, 0-50% EtOAc in hexanes) to give the title compound. MS (ESI pos. ion) m/z: 158.9 (MH-).
With the complex challenges of chemical substances, we look forward to future research findings about 19932-85-5,belong benzoxazole compound
