Procedure

4-[2-(2,2,2-Trifluoroethyl)guanidino]-2-methanesulphinylpyrimidine (140 mg.) was added to a stirred mixture at 50° of t-butanol (10 ml.), NaH (48 mg. of a 50% w/w dispersion in oil) and 1-(2-hydroxyethyl)imidazole, and the mixture stirred at 50° for 2 hours and then evaporated to dryness. The residue was partitioned between aqueous 1N HCl and ether and the aqueous phase basified with aqueous 10N NaOH and extracted with EtOAc. The EtOAc extract was dried and evaporated to dryness and the residue recrystallised from EtOAc to give 1-[2-(4-[2-(2,2,2-trifluoroethyl)guanidino]pyrimid-2-yloxy)ethyl]imidazole (135 mg.), m.p. 149°-150°.
