Abstract

Isonicotinyl hydrazide is made by reacting isonicotinamide in aqueous solution with hydrazine at an elevated temperature, preferably at about 100 DEG C. Suitably a sufficient amount of water is used to form a homogeneous mixture at the reaction temperature, conveniently a quantity of water equal to the weight of the isonicotinamide charge is used, or the amount contained in the commercial hydrazine hydrate. In place of the isonicotinamide, the crude reaction product from the hydrolysis of 4-cyano-4-pyridine according to Specification 776,313 may be used. Examples are given.
