Abstract: Reaction of 2,3 diketoquinoxaline in presence of phosphorus pentachloride and sodium azide in methanol gives 4-hydroxy tetrazolo[1,5-⍺]quinoxaline 3 which on reaction with phosphorous oxychloride gives 4-chloro tetrazolo[1,5-⍺]quinoxaline 4. This on treatment with hydrazine hydrate in ethanol yields 4-hydrazino tetrazolo[1,5-⍺]quinoxaline 5, which on reaction with various aldehydes in DMF gives 4-substituted hydrazinotetrazolo [1,5-⍺]quinoxalines 6a-g. The structures of compounds 6a-g have been confirmed by IR and ¹H NMR.
