Procedure
To a solution of 2-[(4-[[4-nitro-3-(trifluoromethyl)phenyl]amino]cyclohexyl) oxy]acetic acid (100 mg, 0.28 mmol) in dichloromethane (20 ml) was added EDAC.HCl (79.1 mg, 0.41 mmol), HOBt (55.9 mg, 0.41 mmol), triethylamine (83.7 mg, 0.83 mmol) and 6-fluoro-2-(piperazin-1-yl)quinoline (70.2 mg, 0.30 mmol) at room temperature. After stirred overnight, the reaction mixture was then diluted with dichloromethane (100 ml) and washed with water (2×100 ml), dried over anhydrous magnesium sulfate, filtered, and concentrated under vacuum to give a residue, which was purified by a silica gel column with 2% methanol in dichloromethane to afford 1-[4-(6-fluoroquinolin-2-yl)piperazin-1-yl]-2-[(4-[[4-nitro-3-(trifluoromethyl)phenyl]amino]cyclohexyl)oxy]ethan-1-one as a yellow solid (80 mg, 48%); (ES, m/z): [M+H]+ 576.20; 1H NMR (400 MHz, CDCl3): δ 8.02 (d, J=8.8 Hz, 1H), 7.94-7.99 (m, 1H), 7.72-7.78 (m, 1H), 7.31-7.37 (m, 2H), 7.02 (t, J=8.0 Hz, 1H), 6.87 (s, 1H), 6.64 (dd, J=2.4 Hz, 9.2 Hz, 1H), 4.48 (d, J=7.6 Hz, 1H), 4.28 (s, 2H), 3.75-3.81 (m, 7H), 3.41-3.49 (m, 2H), 2.17-2.19 (m, 4H), 1.50-1.58 (m, 2H), 1.28-1.36 (m, 3H).
