Downstream synthetic route of 89891-65-6

89891-65-6, 89891-65-6 7-Bromo-2-chloroquinoxaline 4913253, aquinoxaline compound, is more and more widely used in various fields.

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.
