Preparation of new [1,2,4]triazolo[4,3-b]pyridazines. Part 12: Studies in the field of pyridazine compounds.
6-Substituted-[1,2,4]triazolo[4,3-b]pyridazine-3-methanol, -aldehyde, -nitrile, -chloromethyl and -aminomethyl derivatives of potential antihypertensive activity were synthesized. The reduction of methyl[1,2,4]triazolo[4,3-b] pyridazine-3-carboxylate by lithium aluminium hydride and potassium borohydride was examined. The new compounds failed to exhibit hypotensive or antihypertensive effect. Compound 2a was a minor metabolite of GYKI-11679 [7].
