Versuchsvorschrift

To a solution of 2-[(4-[4-nitro-3-(trifluoromethyl)phenyl]aminocyclohexyl)oxy]acetic acid (900 mg, 2.48 mmol) in dichloromethane (50 ml) was added EDAC.HCl (661 mg, 3.45 mmol), HOBt (464 mg, 3.43 mmol), triethylamine (463 mg, 4.58 mmol) and 1-(2,3-dihydro-1-benzofuran-2-ylmethyl)piperazine (500 mg, 2.29 mmol) in dichloromethane (1 ml) with stirring for overnight at room temperature. Then the mixture was diluted with dichloromethane (300 ml) and washed with water (100 ml). The organic layer was dried over anhydrous magnesium sulfate, filtered, and concentrated under vacuum to give a residue, which was purified by a silica gel column, eluted with 0.5%-3% methanol in dichloromethane to afford 1-[4-(2,3-dihydro-1-benzofuran-2-ylmethyl)piperazin-1-yl]-2-[(4-[[4-nitro-3-(trifluoromethyl)phenyl]amino]cyclohexyl)oxy]ethan-1-one as a yellow solid (462.4 mg, 36%); (ES, m/z): [M+H]+ 563.00; 1H NMR (300 MHz, CDCl3): δ 8.00 (d, J=8.7 Hz, 1H), 7.09-7.18 (m, 2H), 6.77-6.88 (m, 3H), 6.61 (dd, J=2.1 Hz, 8.7 Hz, 1H), 5.03 (broad s, 1H), 4.45 (d, J=6.9 Hz, 1H), 4.20 (s, 2H), 3.67-3.78 (m, 3H), 3.40-3.49 (m, 3H), 2.66-2.99 (m. 6H), 2.13-2.23 (m, 4H), 1.41-1.63 (m, 3H), 1.21-1.34 (m, 3H).
