実験手順
The 3,5,6-trichloro-4-hydrazinopicolinic acid can be prepared in a variety of ways. In one such method, tetrachloropicolinonitrile is reacted with hydrazine in the presence of a reaction medium and hydrogen chloride acceptor. The 3,5,6-trichloro-4-hydrazinopicolinonitrile product thus formed is reacted with an acid hydrolysis agent to prepare 3,5,6-trichloro-4-hydrazinopicolinic acid.
