Reaction Steps

3-(2-Nitrophenylthio)-1,2,4-triazole (4 g) and diethyl carbamoyl chloride (2.71 g) are dissolved in acetone (50 ml) and potassium carbonate (5.5 g) is added, followed by reaction for 5 h under reflux with stirring. After cooling, water (100 ml) is added to the reaction solution, whereupon the crystal of the end product precipitates. After drying, the crystal is recrystallized from ethyl acetate/n-hexane to produce the titled compound, 1-(diethylcarbamoyl)-3-(2-nitrophenylthio)-1,2,4-triazole, in an amount of 5.08 g; yield, 87.8%; m.p. 101°-103° C.
