Substituted-3-hydroxy-pyrid-4-ones, derivatives thereof, and salts thereof are produced by reacting subsituted-3-hydroxypyr-4-one with ammonia or a non-sterically hindered primary amine usually in the presence of a solvent such as water. Also disclosed are novel derivatives of 2-ethyl-3-hydroxypyrid-4-one.
