실험 절차

4-(6-Nitro-pyridin-3-yl)-morpholine (2.86 g, 13.7 mmol) was dissolved in THF (100 mL) to which Raney Nickel (1.03 g) was added. The reaction mixture was shaken under a hydrogen atmosphere (50 psi) for 4 hours. The catalyst was removed by filtration and the solvent evaporated to give 5-morpholin-4-yl-pyridin-2-ylamine as a purple solid (1.91 g, 78.0%). 1H NMR δ (400 MHz, CDCl3) 7.76 (d, J=2.0 Hz, 1H), 7.16 (dd, J=2.7, 8.8 Hz, 1H), 6.50 (d, J=8.8 Hz, 1H), 4.24 (s, 2H), 3.84 (m, 4H), 3.16 (m, 4H), 3.01 (m, 4H).
