(C) 2,6-dichloropyridi ne-3,4-diami neTo a solution of 2,6-dichloro-3-nitropyridin-4-amine in ethanol (150 mL) was added iron powder (14.3 g, 0.255 mol), water (46 mL), and then concentrated HCI (28 mL). The reaction mixture was then stirred at 95 C for 16 hours, cooled to roomtemperature, and neutralized. The precipitates were collected by filtration and dried in vacuo. The crude product was then treated with water (200 mL) and extracted with EtOAc (3 x 200 mL). The combined extracts were dried over anhydrous Na2SO4, filtered, and concentrated to afford 7.85 g of the title compound (86.5% yield).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,2897-43-0, its application will become more common.
