실험 절차

The crude 1-(4-cyanobutyl)-3-amino-1,2,4-triazole (5.45 g.) in acetonitrile (80 ml.) was treated with 2,2,2-trifluoroethylisothiocyanate (4.4 g.) and the solution heated under reflux for 3.5 hours. Evaporation gave a white sticky solid which was triturated with ether/EtOH to give 5-(3-[3-(2,2,2-trifluoroethyl)thioureido]-1,2,4-triazol-1-yl)valeronitrile (4.04 g.) as a white solid, m.p. 136°-138°.
