78% | With iron; acetic acid; at 75℃; for 4h; | 2-Bromo-5-nitropyridin-4-amine (300.0 mg, 2.48 mmol) and Fe (300.0 mg, 5.37 mmol) were added to AcOH, and the reaction mixture was stirred at 75 C. for 4 hours and then cooled to room temperature. The reaction mixture was filtered through celite and then concentrated under reduced pressure. The residue was purified by column chromatography (n-Hex:EtOAc=50:50) on amine silica. The fractions containing the product were collected and concentrated to obtain brown solid compound of 6-bromopyridine-3,4-diamine (200.0 mg, 78%).
