ABSTRACT:
2-Aminopyridine derivatives are prepared by reacting a quaternary ammonium compound with malodinitrile in the presence of an alkanol, followed by reaction with ammonia in the presence of an alkanol, water and/or an ether to give aminonicotinonitrile and, if desired, then reacting this product with an alkali metal compound to give aminonicotinic acid.
The 2-aminopyridine derivatives obtainable by the process of the invention are valuable starting materials for the preparation of pesticides, drugs, vitamins and dyes.
