30 mL N,N-dimethylformamide was charged with 0.01 mol 1-(5-amino-4-bromo-2-fluorophenyl)-3,4-dimethyl-1H-1,2,4-triazol-5(4H)-one. The mixture was stirred until it became clear. 0.02 mol potassium ethyl xanthogenate was added to the mixture in two portions. The mixture was refluxed at 140° C. for 6 h, cooled, and poured into 100 mL ice water slurry. The mixture was acidified with 6 mol/L hydrochloric acid, and a large amount of solid materials crushed out. The title compound was obtained in a 75% yield as a white solid after filtration.
