Reaction Steps
A reaction mixture of 4 g of 2-chloro-3-hydrazinoquinoxaline in 40 ml of triethyl orthoformate was heated at 100° C. for one hour. Upon cooling, the precipitated solid was filtered, washed with cyclohexane, and dried to give 3.9 g of 4-chloro[1,2,4]triazolo[4,3-a]quinoxaline having a mp of 287°-290° C.
