Pyridazines. LIX. Synthesis of c-Annelated Pyridazines from 3-Amino-4-pyridazinecarbonitrile

The utility of the aminonitrile 1 as an educt for the preparation of several new examples of heterocycle-fused pyridazines (the triazolopyrimidopyridazine 7, the pyrimidopyridazines 8, 10a,b, and the pyridopyridazine 11) is demonstrated.
