A Selective Synthesis of 1-Aryl-3-quinoxalinyl-1,2,4-triazole and Furoquinoxaline

The reaction of the ester 1 with ethyl benzoate-2-diazonium chloride gave the α-arylhydrazonoester 2b, whose reaction with hydrazine hydrate afforded the α-arylhydrazonoacylhydrazide 3b.The reaction of 3b with sodium nitrite in water/acetic acid under hea
