3-Methyl-6H-<1,2,4>triazolo<4',3':4,5><1,3,4>thiadiazolo<2,3-b>quinazolin-6-one (6) has been synthesized by the condensation of isatoic anhydride (1) with 4-amino-5-mercapto-3-methyl-<1,2,4>triazole (2) and final cyclisation of the intermediate 3 with POCl3 and PCl3.Alternatively 6 could also be synthesized by the condensation of 3-amino-2-mercapto-3H-quinazolin-4-one (7) with N-carbethoxyhydrazine in presence of hydrochloric acid and final cyclisation of the intermediate 8 with acetic acid.The structures have been confirmed on the basis of IR, PMR and analytical results. - Keywords: Heterocycles; Infrared; 1H-NMR
