| Abstract: | Fenchlorazole ethyl was synthesized in the suitable solvent at 115℃ with α amino (2,4 dichlorophenylhydrono) glyoxylic ethyl ester and trichloroacetic chloride (molar ratio 1∶1) as the raw materials. The synthetic process was simlified by one step of acylation and cycle forming. The yield and purity were 82.4% and more than 95%, respectively. |
