An antihypertensive agent, 2-(2, 6-dichlorobenzylidenehydrazino)-1, 4, 5, 6-tetrahydropyrimidine hydrochloride (OT-24), was obtained by the nuclear reduction of 2-(2, 6-dichlorobenzylidenehydrazino)pyrimidine using palladium-carbon catalyst in acid solution. A number of new tetrahydropyrimidines containing benzylidenehydrazino and benzylhydrazino substituents were synthesized together with several related compounds.
