실험 절차

Cesium carbonate (55.4 mg, 170.0 μmol) was added to ethyl 6-(4-hydroxy-2-methylphenyl)-2-quinolinecarboxylate (47.5 mg, 154.5 μmol) and 4-(chloromethyl)-3-(2,6-dichlorophenyl)-5-(1-methylethyl)isoxazole (51.8 mg, 170.0 μmol) in N,N-dimethylformamide (3.1 mL) at room temperature. The resulting suspension was stirred for eighteen hours, then water added and the reaction mixture was extracted with ethyl acetate. The organic layer was dried over anhydrous magnesium sulfate, then filtered and concentrated. The residue was purified by silica gel chromatography eluting with 3:7 ethyl acetate:hexanes to give 60.2 mg (68%) of ethyl 6-[4-({[3-(2,6-dichlorophenyl)-5-(1-methylethyl)-4-isoxazolyl]methyl}oxy)-2-methylphenyl]-2-quinolinecarboxylate as an oil. 1H NMR (400 MHz, d6-DMSO): δ 8.56 (d, J=9 Hz, 1H), 8.16 (d, J=9 Hz, 1H), 8.13 (d, J=9 Hz, 1H), 7.97 (d, J=2 Hz, 1H), 7.80 (dd, J=9, 2 Hz, 1H), 7.66-7.60 (m, 2H), 7.56 (dd, J=9, 7 Hz, 1H), 7.19 (d, J=8 Hz, 1H), 6.78 (d, J=2 Hz, 1H), 6.73 (dd, J=9, 2 Hz, 1H), 4.86 (s, 2H), 4.43 (q, J=7 Hz, 2H), 3.47 (septet, J=7 Hz, 1H), 2.21 (s, 3H), 1.38 (t, J=7 Hz, 3H), 1.35 (d, J=7 Hz, 6H). ESI-LCMS m/z 575 (M+H)+.
