실험 절차

To a solution of 6-chloro-2-methoxy-3-nitropyridine (283 mg, 1.5 mmol) in acetonitrile/DMF (2:1, 3 mL) was added morpholine (0.13 mL, 1.5 mmol) and triethylamine (0.21 mL, 1.5 mmol). The reaction mixture was stirred at room temperature for 18 hours. The reaction mixture was concentrated in vacuo and the residue was partitioned between water (30 mL) and EtOAc (30 mL). The organic layer was dried (MgSO4) and concentrated in vacuo. The residue was purified by silica gel column chromatography eluting with 20% cyclohexane in EtOAc to give the title compound (280 mg, 78%). 1H NMR (500 MHz, CDCl3): δ 8.28 (d, J=9.0 Hz, 1H), 6.16 (d, J=9.0 Hz, 1H), 4.04 (s, 3H), 3.82 (t, J=4.5 Hz, 4H), 3.71 (t, J=4.5 Hz, 4H).
