3-Pyridazinecarbohydrazide was prepared in a manner analogous to that described above for 6-fluoro-2-pyridinecarbohydrazide (I23) but using 3-pyridazine carboxylic acid (CAS [2164-61-6], commercially available e.g. from Apollo Scientific, Shanghai AOKChem or Manchester Organics) in the place of 6-fluoro-2-pyridinecarboxylic acid.
