Reaction Steps
A solution of 2-chloro-4-((6-nitropyridin-3-yl)oxy)pyridine (20.0 g, 79 mmol) in MeOH (40 mL) was hydrogenated in presence of Raney Nickel (2.00 g, 34.1 mmol) at 40 psi for 3 h. The catalyst was removed via filtration, rinsed with MeOH and the filtrate concentrated to dryness to afford 5-((2-chloropyridin-4-yl)oxy)pyridin-2-amine (18.52 g, 105%) as a brown solid. MS (ESI) m/z: 222.0 (M+H+).
