Procedure

To a solution of methyl 6-{4-[({3-(2,6-dichlorophenyl)-5-[(1S)-1-methylpropyl]-4-isoxazolyl}methyl)oxy]phenyl}-2-quinolinecarboxylate (50 mg, 0.089 mmol) in 2:1 tetrahydrofuran:methanol (1.5 mL) was added 1 N sodium hydroxide (0.13 mL, 0.13 mmol). The solution was heated in a microwave reactor at 80° C. for 10 minutes and then 1 N hydrochloric acid (0.13 mL, 0.13 mmol) was added. The solution was concentrated and the residue was taken up with ethyl acetate and water. The layers were separated and the organic layer was dried over magnesium sulfate and concentrated to afford 50 mg of 6-{4-[({3-(2,6-dichlorophenyl)-5-[(1S)-1-methylpropyl]-4-isoxazolyl}methyl)oxy]phenyl}-2-quinolinecarboxylic acid as a yellow solid (0.089 mmol, 100%). 1H-NMR (400 MHz, DMSO-d6) δ 13.37 (br s, 1H), 8.53 (d, J=9 Hz, 1H), 8.27 (s, 1H), 8.18-8.08 (m, 3H), 7.73 (d, J=9 Hz, 2H), 7.63-7.51 (m, 3H), 6.99 (d, J=9 Hz, 2H), 4.88 (app q, J=12 Hz, 2H), 3.31-3.22 (m, 1H), 1.73-1.66 (m, 2H), 3.32 (d, J=7 Hz, 3H), 0.83 (t, J=7 Hz, 3H). HRMS (ESI) C30H24Cl2N2O4 calculated: 547.1186 (M+H)+, found: 547.1182 (M+H)+.
