Aryl- and alkylhydrazines react with readily availalbe cyclopropanedicarboxylate (2) in refluxing acetonitrile to afford the corresponding 1-substituted 1,4,5,6-tetrahydropyridazin-3(2H)-ones (5) directly via nitrogen-carbon bond formation, cyclization and decarboxlylation of the cyclized intermediates.
