Procedure

Reacting 3-chloropyridazine with 1,3-diaminopropane in ethanol containing sodium ethoxide according to the procedure of Example 89 gives 3-(3-aminopropylamino)pyridazine. Using this intermediate as the starting material in the procedure of Example 18 gives N-cyano-N'-[3-(3-pyridazinylamino)propyl]guanidine.
