Procedure
A mixture of 2-(diaminomethyleneamino)-4-(2-phthalimidomethylpyridin-4-yl)thiazole (1.57 g) and hydrazine hydrate (0.63 g) in ethanol (25 ml) was refluxed for two hours. The resulting precipitate was filtered off and washed with methanol (20 ml). The two organic layer was combined and evaporated in vacuo to give 4-(2-aminomethylpyridin-4-yl)-2-(diaminomethyleneamino)thiazole (1.00 g).
