실험 절차

To a solution of 2-chloro-4-(5-fluoro-2-methyl-4-nitrophenoxy)pyridine (0.48 g, 1.698 mmol) in ethanol (20 mL) was added Raney Ni (0.4 g). The mixture was stirred under a hydrogen atmosphere (1 atm) overnight at RT. The reaction mixture was filtered through a pad of Celite® and the filtrate was concentrated to obtain the crude 4-(2-chloropyridin-4-yloxy)-2-fluoro-5-methylbenzenamine (assuming a 100% yield).
