Two synthetic routes to the versatile 3,5-dihydro-imidazo [4,5-d]pyridazin-4-ones 2 and 5 have been developed that allow the production of multigram quantities without the need of any chromatographic purification. Broad and selective elaboration of the heteroaromatic scaffolds has also been accompli
The title compound 3 was obtained during the rearrangement of isoxazol-5-yl hydrazine 1 to 1 -aminopyrazolone 2 at \(115^{\circ}\). X-ray analysis of the corresponding benzylidene derivative allowed us to achieve the structure assignment.
