With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.89891-65-6,7-Bromo-2-chloroquinoxaline,as a common compound, the synthetic route is as follows.
[0305] To a solution of 7-bromo-2-chloroquinoxaline (10 g, 41 mmol, 1 eq.) in CH3OH ( 200 mL) was added K2C03 ( 12.4 g, 91 mmol, 2 eq). The resulting mixture was stirred under reflux for 2h, then cooled to rt and concentrated. The resulting residue was dissolved in THF and filtered. The filtrate was concentrated to afford 7-bromo-2-methoxyquinoxaline as a white solid (9.88 g, 100%).
89891-65-6, 89891-65-6 7-Bromo-2-chloroquinoxaline 4913253, aquinoxaline compound, is more and more widely used in various fields.
