反応手順

To a solution of 6-chloro-N-(4-ethoxy-2-nitrophenyl)-3-pyridinecarboxamide (50 mg, 0.155 mmol) in DMF (2 ml) was added sodium methoxide (12 mg, 0.222 mmol) in DMF (1 ml) and the reaction mixture was stirred for 10 min. To the mixture was added iodomethane (22 mg, 0.155 mmol) slowly and the mixture was stirred for at room temperature for 3 h. It was diluted with ethyl acetate and washed with water and brine, dried over anhydrous sodium sulfate, and evaporated. The residue was purified by column chromatography to yield the titled compound as a light brown liquid. 1H NMR (CDCl3): 8.17 (d, J=2.1, 1H), 7.68-7.65 (m, 1H), 7.35 (d, J=2.7, 1H), 7.21 (t, J=7.8, 2H), 7.10-7.06 (m, 1H), 4.08-4.01 (m, 2H), 3.40 (s, 3H), 1.44 (t, J=6.9, 3H).
