Procedure

N-(1-(5-Chloro-2,3-dimethoxyphenyl)ethyl)-5-fluoro-2-(methylsulfonyl)benzenamine (100.0 mg, 0.26 mmol), N,N-dimethylpiperidin-4-amine (66.0 mg, 0.51 mmol), N,N-diisopropylethylamine (133.0 mg, 1.03 mmol) were stirred at 100° C. in dry acetonitrile (3 mL) for 16 h. The solvent was evaporated and the residue was dissolved in dichloromethane and washed with water. The dichloromethane was evaporated and the crude compound was purified by silica chromatography using 10% methanol in dichloromethane to afford the title compound (25.0 mg, 19.6% yield). 1H NMR (400 MHz, CDCl3): δ 7.53 (d, 1H), 6.88 (d, 1H), 6.78 (d, 1H), 6.50 (d, 1H), 6.21 (d, 1H), 5.90 (d, 1H), 4.85 (m, 1H), 3.90 (s, 3H), 3.85 (s, 3H), 3.74 (m, 2H), 3.24 (m, 1H), 3.05 (s, 3H), 2.76 (q, 2H), 2.26 (s, 6H), 1.78 (t, 2H), 1.55 (d, 3H), 1.45 (m, 2H); MS (ESI) m/z: 496.1 (M+).
