Simple exploration of 4570-41-6

As the paragraph descriping shows that 4570-41-6 is playing an increasingly important role.

4570-41-6,With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.4570-41-6,Benzo[d]oxazol-2-amine,as a common compound, the synthetic route is as follows.

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.

As the paragraph descriping shows that 4570-41-6 is playing an increasingly important role.
