실험 절차

A mixture of 2-(diaminomethyleneamino)-4-[6-(imino)(methoxy)methylpyridin-2-yl]thiazole (4.0 g) and cyanamide (1.2 g) in methanol (80 ml) was stirred for 16 hours at ambient temperature. To the mixture was added a diethyl ether (80 ml) and isolated precipitate was collected by filtration. The precipitate was added to a mixture of ethyl acetate and water and adjusted to pH 9.5 with 20% aqueous potassium carbonate. The precipitate was collected by filtration and recrystallized from a mixture of N,N-dimethylformamide and ethyl acetate to give 4-[6-(amino)(cyanoimino)methylpyridin-2-yl]-2-(diaminomethyleneamino)thiazole (3.04 g).
