Quinazoline and Their Fused-Ringsystems Are Well Known For Their Potential Biological Activity. Inspired Bythis and In View of the Usefulness of Heterocyclic Thiols As Vulcanizationaccelerators, New Derivatives Viz. Quinazoline-2-Thiols Were Prepared.These Were Synthesized By the Condensation Of 2-[Isothiocyanato(Substituted Phenyl)Methyl]-3,4-Dihydronaphthalene-1(2H)-One With Primaryaromatic Amines. All the Preparedcompounds Have Been Characterized By Elemental Analysis, Ir and Mass Spectroscopy.
