Procedure
A solution of 5-[3-(2-[2,2,2-trifluoroethyl]guanidino)-1,2,4-triazol-1-yl]valeronitrile (0.15 g.) in concentrated sulphuric acid (3 ml.) was stirred for 1.5 hours at room temperature then poured onto ice and basified with concentrated aqueous ammonia. Extraction with EtOAc gave 0.12 g. of a white solid which was triturated with ether to give 5-[3-(2-[2,2,2-trifluoroethyl]guanidino)-1,2,4-triazol-1-yl]valeramide (0.085 g., 54%), m.p. 162°-164°.
