Reactions of 3-Chloro-6-hydrazinopyridazine with Michael-retro-Michael Reagents

Although pyrazole formation results from treatment of 3-chloro-6-hydrazinopyridazine (2) with both ethoxymethylenemalononitrile and ethyl (ethoxymethylene)cyanoacetate, 6-chlorotriazolopyridazine (5) was produced (75percent yield) when 2 was treated with diethyl ethoxymethylenemalonate.Treatment of 2 with diethyl acetylmalonate (8) gave both 6-chloro-3-methyltriazolopyridazine (10) and 5-hydroxy-3-methyl-1-(6-chloro-3-pyridazinyl)-1H-pyrazole-4-carboxylic acid ethyl ester (12).Pyrazole 12 was initially isolated as a salt of triazolopyridazine 10.
