3,3 ': 4 ',3 ''-Ter- 1,2,5-thiadiazole, an useful oligoheterocyclic compound, has been accomplished in seven steps from 1-(5-methyl-3-isoxazolyl)ethanone or diethyl acetylenedicarboxylate using a synthetic utility of tetrasulfur tetranitride antimony pentachloride (S4N4.SbCl5) complex to make a 1,2,5-thiadiazole ring.
