Versuchsvorschrift

A reaction mixture of 5 g of 2-chloro-3-hydrazinoquinoxaline in 15 ml of triethyl orthobutyrate was heated at 100° C. for three hours. Upon cooling, the precipitated solid was filtered, washed with cyclohexane, and dried giving 4.0 g of 4-chloro-1-propyl[1,2,4]triazolo[4,3-aquinoxaline having a mp of 172°-175° C.
