反応手順
A solution of 4-(5-acetylaminomethylfuran-2-yl)-2-(diaminomethyleneamino)thiazole (4.76 g) in 1N-hydrochloric acid (51.1 ml) was refluxed for 8 hours with stirring. The solution was made basic to pH 10 with an aqueous potassium carbonate. The resulting precipitate was collected by filtration and washed with water to afford 4-(5-aminomethylfuran-2-yl)-2-(diaminomethyleneamino)thiazole (4.03 g).
