69% | With palladium diacetate; caesium carbonate; XPhos; at 100℃; for 15h;Microwave irradiation; Inert atmosphere; | <strong>[126717-59-7]3-bromo-6-methoxy-2-methylpyridine</strong> (Aldrich catalog No.758191-1G,0.3 g, 1.485 mmol), 2-(dicyclohexylphosphino)-2',4',6'-tri-i-propyl-1,1'-biphenyl (0.053 g, 0.111 mmol), cesium carbonate (0.581 g, 1.782 mmol) and palladium (II) acetate (0.017 g, 0.074 mmol) were added to a microwave vial. Then, 2-chloro-5-methoxyaniline (Chemimpex catalog No.27675, 0.246 g, 1.559 mmol) was added. The solvent was degassed with argon twice. The reaction was heated on a heating block to 100 C. for 15 hours. The crude reaction mixture was cooled to room temperature and then filtered through celite. The celite was rinsed repeatedly with ethyl acetate to collect the crude product mixture. A reverse-phase column was run (water, acetonitrile) to give N-(2-chloro-5-methoxyphenyl)-6-methoxy-2-methylpyridin-3-amine (0.286 g, 69% yield). 1H NMR (CDCl3, 400 MHz) delta 7.42 (d, 1H, J=8.4 Hz), 7.20 (d, 1H, J=8.4 Hz), 6.60 (d, 1H, J=8.4 Hz), 6.26 (dd, 1H, J=2.8, 8.8 Hz), 6.00 (d, 1H, J=2.8 Hz), 5.65 (s, 1H), 3.93 (s, 3H), 3.66 (s, 3H), 2.37 (s, 3H). |
