Process for producing 2-(methylthio)-5-(trifluoromethyl)-1,3,4-thiadiazole using methyldithiocarbazinate and trifluoroacetic acid

摘要

The present invention provides a process of making 2-(methylthio)-5-(trifluoromethyl)-1,3,4-thiadiazole. The process includes the steps of (a) reacting methyldithiocarbazinate with a molar excess of trifluoroacetic acid; and (b) removing the water and excess trifluoroacetic acid. Water and excess trifluoroacetic acid are preferably removed via distillation.
