Description
Summary:Reaction of 4,6-diamino-2(1H)-pyrimidinethione (1) with p-toluene-sulfonyl hydrazine, nitrous acid and carbon disulfide afforded the compounds (2, 3) and (4) respectively. Compound (3) easily reacted with anthranilic acid, semicarbazide thiosemicarbazide and acid hydrazides and gave the polynuclearheterocyclic compounds (5, 6 a,b ) and (8 a,b ) respectively. Also, compound (4) yielded the tricyclic compound 7 when reacted with ethylchloroformate. The purpose of this article is synthesis of biologically active polynuclear heterocyclic compounds.
