PROCESS FOR PREPARING 3-TRICHLOROMETHYL-5-ETHOXY-1,2,4-THIADIAZOLE FROM TRICHLOROACETONITRILE

摘要

ABSTRACTA process for preparing 3-trichloromethyl-5-ethoxy-1,2,4-thiadiazole by reacting trichloroacetonitrile with ammoniain the presence of ethanol; adding trichloromethanesulfenylchloride to the reaction mixture and permitting the reaction toproceed until the resulting exotherm has ceased; and then addinga base and recovering 3-trichloromethyl-5-ethoxy-1,2,4-thiadiazole.
