Current trends in the search for new biologically active compounds among synthetic molecules have arguably proved a priority in studies of the heterocyclic 1,2,4-triazole system. For many years, 1,2,4-triazole derivatives remain the object of close attention of scientists of various scientific fields. The unique properties of 1,2,4-triazole derivatives include high reactivity, which allows different modification of this system, practical absence of toxicity of these derivatives and the presence of a wide range of biological, pharmacological properties, which in the complex provides the prerequisites for the creation of new biologically active compounds, and in the future, active pharmaceutical ingredients (AFI). The aim of our work is to investigate some transformations in a number of derivatives of 5-(thiophen-3-ylmethyl) -4-R1-1,2,4-triazole-3-thiol, to study the physicochemical properties of the new synthesized compounds. A well-known fact remains the successful attempt of many scientists involved in the study of the heterocyclic 1,2,4-triazole system to synthesize potential biologically active compounds. The process of creating new molecules is very painstaking and requires considerable effort. The chemical approaches for the synthesis of the starting compounds required for further transformations are well known and described. Therefore, we used the corresponding N-R1-2 as intermediates for the synthesis of new 5-(thiophen-3-ylmethyl) -4-R1-1,2,4-triazole-3-thiols appropriate ones were used N-R1-2-(2-(thiophen-3-yl) acetyl) hydrazinocarbothioamide.
