Özet:

 

The 1H-pyrazole-3-carboxylic acid 2, obtained from the  furandione 1 and 2-hydrazinopyridine, was decarboxylated to give  4-benzoyl-5-phenyl-1-pyridin-2-yl-pyrazole derivative 3.  Some ester 4  derivatives of 2 were prepared by the Fischer esterification reactions  of 2 with various alcohols.  Cyclocondensation reactions of 2 with  phenyl hydrazine or hydrazine hydrate led to the formation of  derivatives of pyrazolo[3,4-d]pyridazine 5 derivatives.
