| Zusammenfassung: | The invention provides a process for preparing a 4-amino-5-mercapto-3-substituted-[1,2,4]triazole comprising reacting a thiocarbohydrazide with a carboxylic acid in the presence of an organic solvent and a boron compound having the formula where R2, R3, and R4 are independently selected from the group consisting of hydrogen, hydroxy, amino, alkyl, aryl, alkoxy, and aryloxy groups. The process provides a safer low temperature process for preparing the desired compound. |
