The 1H-pyrazole-3-carboxylic acid 2 or its remarkably stable acid chloride 3 can easily be converted into the corresponding ester or amide derivatives 4 or 5, respectively, from reaction with alcohols or N-nucleophiles. Pyrazolo[3,4-d]pyridazines 6a,b are obtained from cyclocondensation reactions of the pyrazoles 2 and 3, respectively, with phenylhydrazine or hydrazine hydrate, while 6c is formed in an one-pot procedure from the furan-2,3-dione 1 and hydrazine hydrate.
