A mixture of 2-(7-methoxy-6-nitro-quinolin-2-ylamino)-ethanol (0.5 g, 1.90 mmol), iron powder (0.32 g, 5.70 mmol) and ammonium chloride (0.32 g, 5.70 mmol) in a mixture of ethanol and water (3/1, 16 mL) was heated at reflux for 2 hours. The reaction mixture was then filtered through a CELITE™ pad, the filtrate was evaporated under reduced pressure and the residue was triturated ten times with a mixture of dichloromethane and methanol (9/1, 50 mL). The residue was concentrated under reduced pressure to afford 0.425 g of 2-(6-amino-7-methoxy-quinolin-2-ylamino)-ethanol as a brown solid.
