Procedure

To 2-[2-(2,2,2-trifluoroethyl)guanidino]-4-[5-(3-cyano-2-methylisothioureido)pentyl]thiazole (0.25 g.) in ethanol (1 ml.) was added ethanolic methylamine (33% w/v, 30 ml.). The mixture was allowed to stand overnight at room temperature and then evaporated to dryness to give 2-[2-(2,2,2-trifluoroethyl)guanidino]-4-[5-(3-cyano-2-methylguanidino)pentyl]thiazole. The n.m.r. spectrum in d6 dimethylsulphoxide containing tetramethylsilane as internal standard (δ=0) included the following resonances (δ): 1.5 (multiplet, 6H); 2.7 (doublet, 3H); 3.1 (multiplet, 2H); 4.1 (multiplet, 2H); 6.4 (singlet, 1H).
