반응 단계
It is known that 4-amino-3,5,6-trichloropicolinic acid is prepared by a two-step method where heptachloro-2-picoline is aminated with anhydrous liquid ammonia to form 4-amino-hexachloro-2-picoline, an intermediate product that is isolated, and which is in turn hydrolyzed with sulfuric acid to form 4-amino-3,5,6-trichloropicolinic acid. See, for example, Russian Pat. No. 445,662.
