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.,4570-41-6
1.34 g (10 mmol) benzo [d] oxazol-2-amine and3.07 g (10 mmol) of 1- (2,2-dibromovinyl) -2-nitrobenzene was dissolved in80 mL of dimethylformamide (DMF)Then stirred at a temperature of 120 ¡ã C for about 12 hours.The resulting reaction solution was cooled to room temperature.The organic layer was then extracted three times with 30 mL of water and 30 mL of ethyl acetate.The collected organic layer was dried with magnesium sulfate and the solvent was evaporated.The resulting residue was separated and purified by silica gel column chromatography, thereby completing the preparation of 1.87 g (75percent) of the intermediate I-1.
With the complex challenges of chemical substances, we look forward to future research findings about 4570-41-6,belong benzoxazole compound
