FACILE SYNTHESIS OF NOVEL 3-(4-AMINO-5-METHYL-4H-1,2,4-TRIAZOL-3-YLMETHYLENE)-2-OXO-1,2,3,4-TETRAHYROQUINOXALINE AND RELATED COMPOUNDS

The reaction of the hydrazone (3a) with hydrazine hydrate in DBU/EtOH conveniently gave novel 3-(4-amino-5-methyl-4H-1,2,4-triazol-3-ylmethylene)-2-oxo-1,2,3,4-tetrahydroquinoxaline (6), which was converted into the various new 1,2,4-triazole derivatives
