Procedure
A mixture of methyl 5-[2-(2-[2,2,2-trifluoroethyl]guanidino)thiazol-4-yl]valerate (0.4 g.) and ethanolic methylamine (33% w/v, 60 ml.) was allowed to stand at room temperature for 2 days. The mixture was then evaporated to dryness and the residue recrystallised from EtOAc/ether to give N-methyl-5-[2-(2-[2,2,2-trifluoroethyl]guanidino)thiazol-4-yl]valeramide (yield 85%), m.p. 122°-126°.
