実験手順

To a solution of 5-(3-[3-(2,2,2-trifluoroethyl)thioureido]pyrazol-1-yl)valeramide (0.5 g.) in 6 M ammonia in ethyl alcohol (6 ml.) was added mercuric oxide (0.56 g.) over 5 minutes. The mixture was stirred for 1 hour and filtered. The filtrate was evaporated in vacuo to an oil which was dissolved in EtOAc. Addition of petroleum ether (b.p. 60°-80°) gave 5-[3-(2-[2,2,2-trifluoroethyl]guanidino)pyrazol-1-yl]valeramide as a crystalline solid, m.p. 128°-132°.
