| Abstract: | Reactions of 3-oxo-N-phenylbutanethioamide with 3-substituted 5-amino-1H-1,2,4-triazoles in acetic acid led to the formation of 5-methyl-7,8-dihydro1,2,4]triazolo1,5-a]pyrimidine-7-thiones, 7-methyl-5,8-dihydrol1,2,4]triazolo1,5-a]pyrimidine-5-thiones and 7-methyl-5-phenylamino1,2,4]triazolo1,5-a]pyrimidines. The structure of the products was proved by the 1H and 13C NMR spectra, X-ray diffraction data, and chemical transformations. |
