実験手順

Add bis(4-methoxybenzyl)amine (35.7 g, 138.9 mmol) in 20 mL of N-methylpyrrolidone to a solution of 2,6-dichloro-3-trifluoromethylpyridine (20 g, 92.6 mmol) and triethylamine (19.4 mL, 138.9 mmol) in 100 mL of N-methylpyrrolidone. Raise the temperature to 120° C., and stir the reaction for 14 hours. Quench the reaction mixture by the addition of water (80 mL), followed by extraction with EtOAc (3×70 mL). Wash the combined organic extracts with water (2×70 mL) and brine (70 mL), and dry over anhydrous Na2SO4. Filter the dried extract and concentrate under vacuum to afford the crude product, which is purified by column chromatography to give a yellow solid. 1H NMR (400 MHz, CDCl3) δ 7.58 (d, 1H, J=8.4 Hz), 7.15 (m, 4H), 6.85 (m, 4H), 6.31 (d, 1H, J=8.8 Hz), 4.70 (s, 4H), 3.80 (s, 6H). Mass spec. (436.99, M+H).
