Reaction Steps

A suspension of 2-(diaminomethyleneamino)-4-[2-(imino)(methoxy)methylthiazol-4-yl]thiazole (1.0 g) and sulfamide (1.36 g) in a 2-methoxyethanol (10 ml) was heated at 70° C. for 7 hours. The resulting precipitate was removed by filtration. The filtrate was chromatographed on a silica gel column eluting with ethyl acetate:methanol=3:1. Recrystallization from a mixture of N,N-dimethylformamide and water afforded 4-[2-(amino)(aminosulfonylimino)methylthiazol-4-yl]-2-(diaminomethyleneamino)thiazole (0.35 g).
