YieldReaction ConditionsOperation in experiment
70% With dmap; 1-ethyl-(3-(3-dimethylamino)propyl)-carbodiimide hydrochloride; In dichloromethane; at 20℃; To a solution of 6-ethoxypicolinic acid (2.2 g, 13.2 mmol, 1 equiv) and 2,6- dimethoxyaniline (2.2 g, 14.5 mmol, 1.2 equiv) in DCM (40 mL) were added DMAP (80 mg, 0.6 mmol, 0.05 equiv) and EDCI (3.0 g, 15.8 mmol, 1.2 equiv) successively at room temperature. The resulting mixture was stirred at room temperature overnight. The reaction was diluted with EtOAc (300 mL) and water (3*100 mL). The organic layers were separated, washed with brine (100 mL), dried over anhydrous Na2S04, and concentrated in vacuo. The residue was purified by flash column chromatography (eluted with PE/ EtOAc = 20/1-1/1) to afford the title compound N-(2,6-dimethoxyphenyl)-6-ethoxypicolinamide as a white solid (2.8 g, 70% yield). NMR (400 MHz, DMSO-de) d 9.35 (s, 1H), 7.89 (t, J = 7.6 Hz, 1H), 7.64 (d, J = 7.2 Hz, 1H), 7.26 (d, J = 8.4 Hz, 1H), 7.03 (d, J = 8.0 Hz, 1H), 6.73 (d, J = 8.4 Hz, 2H), 4.47 (q, J = 7.2 Hz, 2H), 3.75 (s, 6H), 1.35 (t, J = 7.2 Hz, 3H).
