Synthesis of tetrazolo [1,5-a]quinoxaline derivatives

Abstract

Displacement reaction of 2,3-dichloroquinoxaline with secondary amines in boiling ethanol afforded it`s mono aminoquinoxaline derivatives. Further reaction of the latter compounds with sodium azide in warm dimethylsulfoxide achieved a group of 4-amino tetrazolo[1,5-<em>a</em>]quinoxaline derivatives. 1HNMR spectra of these compounds are discussed.
