実験手順

4-Cyanobutanol (10 g.) was added to sodium hydride (2.75 g.) in t-butanol (95 ml.) and the solution warmed to 40°. 4-[2-(2,2,2-Trifluoroethyl)guanidino]-2-methylsulphinylpyrimidine (European patent publication No. 30092) was added over 10 minutes and the solution kept at 40° for 2 hours then at room temperature for 18 hours. The solvent was removed under vacuum and the residue washed with water, then ether, to give 5-[4-(2-[2,2,2-trifluoroethyl]guanidino)pyrimid-2-yloxy]valeronitrile (8.5 g.), m.p. 134°-136°.
