Participants

Reaction Steps

A solution of 2-(diaminomethyleneamino)-4-[5-(2-methyl-3-isothioureido)methylfuran-2-yl]thiazole hydriodide (1.0 g), cyanamide (120 mg) and triethylamine (1.2 g) in N,N-dimethylformamide (20 ml) was heated at 100° C. for 3 hours. The solvent was removed under reduced pressure. The residue was chromatographed on a silica gel column eluting with a mixture of chloroform and methanol (20:1, V/V). Recrystallization from 20% methanol afforded 2-(diaminomethyleneamino)-4-[5-(2-cyanoguanidino)methylfuran-2-yl]thiazole (170 mg).
