Methyl 5-(4-[2-(2,2,2-trifluoroethyl)guanidino]pyrimid-2-yloxy)valerimidate (1.5 g.) in MeOH (15 ml.) was treated with ammonium chloride (0.25 g.) and the solution stirred at room temperature for 2 hours. Ether was added until the solution became cloudy. Continued stirring caused precipitation of a solid which was filtered to give 5-(4-[2-(2,2,2-trifluoroethyl)guanidino]pyrimid-2-yloxy)valeramidine hydrochloride, (1.52 g.), m.p. 156°-158°.
