2-(5-imino-4-aryl-4,5-dihydro-[1,3,4]-thiadiazole-2-(carbonyl)benzo[f]chro-men-2-one, 2-(2-amino-5-arylazothiazol-4-yl)benzo[f]chromen-3-one and ethyl 6-methyl-3oxo-benzo [f]chromen-2-yl)-1,4-dihydro-[1,2,4]triazolo[4,3-a]pyrimidine-5-carboxylate were synthesized from hydrazonoyl bromides. Structures of the newly synthesized compounds were established by elemental analysis, spectral data and alternative synthesis route whenever possible.
