3,5-Difluoro-2-pyridinecarbohydrazide was prepared in a manner analogous to that described above for 6-fluoro-2-pyridinecarbohydrazide (I23) but using 3,5-difluoro-2-pyridinecarboxylic acid (CAS [745784-04-7], commercially available e.g. from Matrix Scientific, Alfa Aesar or Apollo Scientific) in the place of 6-fluoro-2-pyridinecarboxylic acid.
