Procedure
A mixture of 2-(diaminomethyleneamino)-4-[5-(3-cyano-2-methyl-1-isothioureido)methylfuran-2-yl]thiazole (1.10 g) and monoethanolamine (1 ml) in N,N-dimethylformamide (10 ml) was stirred at 70° C. for 7 hours. The solvent was evaporated in vacuo and the residue was mixed with water. The resulting precipitate was collected by filtration, washed with water and recrystallized from a mixture of dioxane, methanol and diisopropyl ether to afford 4-[5-{2-cyano-3-(2-hydroxyethyl)guanidino}methylfuran-2-yl]-2-(diaminomethyleneamino)thiazole (0.80 g).
