실험 절차

A mixture of 2-(diaminomethyleneamino)-4-(6-propionylaminomethylpyridin-2-yl)thiazole (49.0 g) and conc. hydrochloride acid (134 ml) in ethanol (500 ml) was heated under reflux for 7 hours and after the mixture was cooled to ambient temperature. To the mixture was added ethanol (500 ml) with stirring and the isolated precipitate was collected by filtration to give 4-(6-aminomethylpyridin-2-yl)-2-(diaminomethyleneamino)thiazole trihydrochloride (52.36 g).
