The 3-hydrazinylquinoxalin-2-ol (2) and 2,3-dichloroquinoxaline (3) were prepared from2,3-dihydroxyquinoxaline (4) and used as an intermediates in the syntheses of triazoloquinoxaline, imidazoquinoxaline, tetrazoloquinoxaline and piperazinoquinoxalines ring systems.

This study demonstrates the use of 2,3-hydrazinylquinoxalin-2-ol as an intermediate in the synthesis of fused quinoxaline ring systems, providing a new approach for the synthesis of triazoloquinoxaline, imidazoquinoxaline, t
