INTERMEDIATE: 4-Chloro-l -(2-chloro-phenyl)-[l ,2,4]triazolo[4,3-a]quinoxaline (IIx). A mixture of 2-chloro-3-methoxyquinoxaline (455 mg) and 2-chlorobenzhydrazide (439 mg) in acetonitrile (10 mL) was heated at 150 C for 15 min under MW conditions. The reaction mixture was cooled in an ice/water bath and the precipitated solid was collected by filtration. This material was suspended in acetonitrile (10 mL) and phosphoryl chloride (1.09 mL) was added. The mixture was heated at 150 C for lh under MW conditions, before another 0.5 mL of phosphoryl chloride was added and the mixture was heated for an additional lh at 150 C under MW conditions. The reaction mixture was poured onto ice and diluted with ice/water to a final volume of 50 mL. It was neutralized with solid NaHC03 and the resulting yellow precipitate was collected by filtration, water and dried to afford IIx (409 mg).
32998-25-7, 32998-25-7 2-Chloro-3-methoxyquinoxaline 20227409, aquinoxaline compound, is more and more widely used in various fields.
