Procedure
A mixture of 2-(diaminomethyleneamino)-4-[5-(2-cyano-3-methylguanidino)methylfuran-2-yl]thiazole (2.28 g) and 4M-dioxanic hydrogen chloride (10 ml) in methanol (20 ml) was stirred at ambient temperature for 19 hours and further at 50° C. for 5 hours. The resulting precipitate was collected by filtration, washed with methanol, and recrystallized from a mixture of methanol and water to afford 2-(diaminomethyleneamino)-4-[5-(2-carbamoyl-3-methylguanidino)methylfuran-2-yl]thiazole dihydrochloride (1.65 g).
