Reaction of the furopyrido-as-triazinium salt 1 with methyl hydrazine gave the zwitterionic 1-substituted pyrido-pyridazino-as-triazine 4.The neutral 2-substituted isomer 6 was formed when 1 was treated with 1-formyl-1-methyl-hydrazine.Reaction of 1 with 1-acyl-2-methylhydrazine gave rise to 1,3,4-trisubstituted zwitterionic derivatives of the same ring system.Efforts to synthesize aryl-substituted zwitterions led to simultaneous formation of the desired compound 12 and of a new ring transformation product, the pyrazolopyrido-as-triazine derivative 15.
