Reaction Steps
A mixture of 2-(diaminomethyleneamino)-4-(6-methoxycarbonylpyridin-2-yl)thiazole (4.0 g) and 100% hydrazine monohydrate (1.05 ml) in ethanol (40 ml) was heated under reflux for 8 hours. To the reaction mixture was added ethyl acetate (60 ml) under stirring at ambient temperature. The isolated precipitate was collected by filtration to give 2-(diaminomethyleneamino)-4-(6-hydrazinocarbonylpyridin-2-yl)thiazole (3.19 g).
