Reaction Steps

A reaction mixture of 5 g of 2-chloro-3-hydrazinoquinoxaline in 50 ml of triethyl orthoacetate was heated at 100° C. for three hours. Upon cooling, the precipitated solid was filtered, washed with cyclohexane, and dried affording 4.27 g of 4-chloro-1-methyl[1,2,4]triazolo[4,3-a]quinoxaline having a mp of 215°-218° C.
