With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.108229-82-9,6-Bromo-2,3-dichloroquinoxaline,as a common compound, the synthetic route is as follows.
General procedure: A mixture of substituted 7,8-dimethoxytetrazolo-[1,5-a]-quinazolin-5-amine 4 (0.001 mol) and 2,3-dichloroquiaxoline 2a-e (0.01 mol) in glacial acetic acid 10 mL containing 0.2 mL of DMF as a catalyst wa refluxed for 12-15 hr. after completion of the reaction (monitored by TLC), the reaction mixture was poured into water, the solid separated was filtered, washed with water, dried and purified by column chromatodraphy (2:8 CHCl3:EA) to furnish the desired compounds 5a-e.
108229-82-9, 108229-82-9 6-Bromo-2,3-dichloroquinoxaline 13799585, aquinoxaline compound, is more and more widely used in various.
