30 mL N,N-dimethylformamide was charged with 0.01 mol 1-(5-amino-2,4-dichlorophenyl)-4-(difluoromethyl)-3-methyl-1H-1,2,4-triazol-5(4H)-one. The mixture was stirred until it became clear. Then, 0.02 mol potassium ethyl xanthogenate was added to the mixture in two portions. The mixture was refluxed at 140° C. for 5 h, cooled, and poured into 100 mL ice water. Then, the mixture was acidified with 6 mol/L hydrochloric acid, and a large amount of solids crushed out. The title compound was obtained in a 68% yield as a white solid after filtration.
