Reaction Steps

A suspension of 2-(diaminomethyleneamino)-4-(5-methoxycarbonylpyridin-3-yl)thiazole (500 mg) in 28% ammonia solution (15 ml) and tetrahydrofuran (15 ml) was stirred at room temperature for 9.5 hours. The solvent was removed under reduced pressure. The residue was washed with methanol to afford 4-(5-carbamoylpyridin-3-yl)-2-(diaminomethyleneamino)thiazole (350 mg).
