Reaction Steps
To a solution of 4-(benzyloxy)-3-nitropyridine (42.0 g, 0.18 mol), Fe (30.6 g, 0.55 mol) and NH4Cl (48.8 g, 0.91 mol) in MeOH:THF:H2O=(2:2:1, 750 mL) was stirred at reflux for 3 h. After being filtered and concentrated in vacuum, the residue was purified by column chromatography (DCM:MeOH=10:1) to give to give the pure 4-(benzyloxy)pyridin-3-amine (29.5 g, yield: 80.7%). 1H-NMR (CDCl3, 400 MHz) δ 8.25 (s, 1H), 7.88 (s, 1H), 7.20˜7.65 (m, 5H), 6.89 (s, 1H), 5.18 (s, 2H). MS (M+H)+: 201.
