, p. 5186 - 5190 (2014)
Although desirable from a medicinal chemistry perspective, the differentially substituted 3,6-diaminopyridazine moiety is a highly challenging target using current literature approaches. Recent methods of Ullmann-type couplings are evaluated and a mild route to prepare these structures from iodide precursors is presented.

Compounds useful as schistosomicidal agents are cyclic alkylidenyl N-[6-(R3 R4 N)-4(or 5)-R5 -3-pyridazinyl]aminomethylenemalonates (I), where R3 R4 N is lower-tertiary-amino and R5 is hydrogen or lower-alkyl, are prepared by reacting 3-amino-6-(R3 R4 N)-4(or 5)-R5 -pyridazine (III) with cyclic alkylidenyl α-(lower-alkoxymethylene)malonate (IV) or by heating equimolar quantities of III, tri-(lower-alkyl) orthoformate and cyclic alkylidenyl malonate (V). Also shown is cyclic isopropylidenyl N-(6-methylamino-3-pyridazinyl)aminomethylenemalonate, a schistosomicidal agent, and its preparation. Also shown are schistosomicidal compositions comprising as active component a schistosomicidally effective cyclic alkylidenyl N-[6-(R3 R4 N)-4(or 5)-R5 -3-pyridazinyl]aminomethylenemalonate (I) or cyclic isopropylidenyl N-(6-methylamino-3-pyridazinyl)aminomethylenemalonate (II) or salt thereof and a method for the treatment of schistosomiasis which comprises administering to a host infected with schistosomes a schistosomicidally effective amount of said active component.
