HCID 450843134-Methylpyridine-2-carbohydrazide

Procedure

4-Methyl-2-pyridinecarbohydrazide was prepared in a manner analogous to that described above for 6-fluoro-2-pyridinecarbohydrazide (I23) but using 4-methyl-2-pyridinecarboxylic acid (CAS [4021-08-3], commercially available e.g. from Sigma-Aldrich or Fluorochem) in the place of 6-fluoro-2-pyridinecarboxylic acid.
