A Novel Approach to the Synthesis of 1,3,4-Thiadiazole-2-amine Derivatives
The main purpose of the study was the development of a new method for synthesis of 1,3,4-thiadiazol-2-amine derivatives in a one-pot manner using the reaction between a thiosemicarbazide and carboxylic acid without toxic additives such as POCl3 or SOCl2.
