Reaction Steps

A mixture of 2-(diaminomethyleneamino)-4-[6-(imino)(methoxy)methylpyridin-2-yl]thiazole (2.1 g) and sulfamide (2.9 g) in 2-methoxyethanol (10.5 ml) was stirred for 3 hours at 70°-75° C. The mixture was added to water, isolated precipitate was collected by filtration and dried. The precipitate was recrystallized from a mixture of N,N-dimethylformamide and ethyl acetate to give 4-[6-(amino)(aminosulfonylimino)methylpyridin-2-yl]-2-(diaminomethyleneamino)thiazole (1.28 g).
