Procedure

A solution of hydrogen chloride in dioxane (4N, 5 ml) was added slowly to a suspension of 4-(2-t-butoxycarbonylaminoacetylaminomethylthiazol-4-yl)-2-(diaminomethyleneamino)thiazole (1.0 g) in methanol (5 ml) with cooling on an ice-water bath. The mixture was stirred for 24 hours with cooling on an ice-water bath. The resulting precipitate was collected by filtration. Recrystallization from a mixture of methanol and diisopropyl ether afforded 4-(2-aminoacetylaminomethylthiazol-4-yl)-2-(diaminomethyleneamino)thiazole dihydrochloride (0.58 g).
