Abstract:1H-1,2,4-triazole derivatives,owing to their extensive uses in pharmaceutical synthesis,in an effort to search for more useful reaction intermediates containing 1H-1,2,4-triazole, four new 5-substituted-1H-1,2,4-triazoles were synthesized from 5-amino-1H-1,2,4-triazole-3-carboxylic acid ethyl ester by Sandmeyer reaction. Their structures were confirmed by elementl analysis, IR, UV and ~1 HNM. |
Key words:5-amino-1H-1; 2; 4-triazole-3-carboxylic acid ethyl ester; Sandmeyer reactipn; synthesis; characterization |
