Polynuclear thieno[2,3-d]pyrimidone derivatives had been synthesized by an intermolecular reaction of 2-hydrazino-thieno[2,3-d]pyrimidin-4-one (1) with each of the aliphatic acids, and carbon disulfide afforded thienotriazolepyrimidin-5-one derivatives. On the other hand, compound 1 that condensed with α-haloketone yielded thienopyrimidotriazine, and with β-diketones and β-ketoesters formed 2-(1-pyrazolyl)
