Pyridazine derivatives and related compounds. Part 13: Synthesis and antimicrobial activity of some pyridazino[3′,4′:3,4]pyrazolo[5,1-c]- 1,2,4-triazines

Pyridazinopyrazolotriazine A general method for the preparation of substituted pyridazinopyrazolotriazines is reported. 3-Aminopyrazolo[3,4-d] pyridazine was diazotized and coupled with active methylene reagents to afford the tricyclic pyridazino[3′,4′:3,
