Analyzing the synthesis route of 50998-17-9

50998-17-9 6-Bromoquinoxaline 610939, 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.50998-17-9,6-Bromoquinoxaline,as a common compound, the synthetic route is as follows.

50998-17-9, To 6-bromo-quinoxaline (1 g) in acetonitrile (25 mL) was added propargyl alcohol (0.285 mL) and triethylamine (1.334 mL) followed by copper(I) iodide (10 mg) and bis(triphenylphosphine)palladium chloride (34 mg). The reaction mixture was stirred under nitrogen and then heated at 800C for 18h. The mixture was allowed to cool and then filtered. The filtrate was evaporated and then purified by chromatography on silica eluting with ethylacetate / isohexane (1 : 1 to 1 : 0) to afford the sub-titled compound as a solid (0.7 g).1H NMR (400 MHz, DMSO) I’ 8.97 (2H, dd), 8.13 (IH, d), 8.10 (IH, d), 7.84 (IH, dd), 5.45 (IH, t), 4.39 (2H, d).
