실험 절차

4-(4-Fluorophenyl)-7-methylquinoline-2-carbonitrile (1-6, 25 mg, 0.095 mmol, 1.0 equiv.) was dissolved in acetone (2.3 mL)/water (1.5 mL) and sodium percarbonate (79.0 mg, 0.477 mmol, 5.0 equiv) was added. The resulting mixture was stirred at 50° C. for 1 hour. The mixture was cooled and concentrated. The crude residue was purified by reverse phase HPLC (H2O/CH3CN gradient w/0.1% TFA modifier). Fractions containing product were pooled and treated with Na2CO3. The resulting mixture was extracted with CHCl3. The combined organic layers were dried (MgSO4), filtered, and concentrated to afford 4-(4-fluorophenyl)-7-methylquinoline-2-carboxamide (1-7). LRMS m/z (M+H)+ 280.9 found, 281.3 required.
