실험 절차

To a room temperature solution of 7-({4-[cyclopropyl(hydroxy)methyl]-1H-pyrazol-1-yl}methyl)-4-(4-fluorophenyl)quinoline-2-carboxamide (3-10, 22 mg, 0.053 mmol, 1.0 equiv.) in methylene chloride (1.0 mL) was added Dess-Martin Periodinane (67.2 mg, 0.158 mmol, 3.0 equiv.) and the mixture was stirred at room temperature overnight. Aqueous Na2S2O3 (saturate, 2.0 mL) and aqueous sodium hydrogen carbonate (saturate, 5.0 mL) were added and the mixture was extracted with ethyl acetate (3×5 mL). The combined organic layers were washed with brine, dried over MgSO4, filtered and concentrated. The residue was purified by reverse phase HPLC (H2O/CH3CN gradient w/0.1% TFA modifier) to afford 7-{[4-(cyclopropylcarbonyl)-1H-pyrazol-1-yl]methyl}-4-(4-fluorophenyl)quinoline-2-carboxamide (3-11, 3.30 mg, 15.1%) as a colorless solid. 1H NMR (400 MHz, CDCl3): δ 8.239 (s, 1H); 8.179 (br s, 1H); 8.088 (s, 1H); 8.039 (s, 1H); 8.017 (s, 1H); 7.965 (d, J=8.81 Hz, 1H); 7.466-7.510 (m, 3H); 7.219-7.263 (m, 2H); 6.369 (br s, 1H); 5.585 (s, 2H); 2.283-2.345 (m, 1H); 1.187-1.225 (m, 2H); 0.958-1.004 (m, 2H). LRMS m/z (M+H)+ 415.2 found, 415.2 required.
