To a solution of methyl 6-[4-({[3-{[(2,6-dichlorophenyl)(trifluoroacetyl)amino]methyl}-5-(1-methylethyl)-4-isoxazolyl]methyl}oxy)phenyl]-2-quinolinecarboxylate (10 mg, 0.015 mmol) in 1:1 tetrahydrofuran:methanol (0.75 mL) was added 1 N sodium hydroxide (0.37 mL, 0.37 mmol). The solution was heated in a microwave reactor at 90° C. for 10 minutes. The solution was concentrated and the residue was taken up with ethyl acetate. Then 1 N hydrochloric acid (0.37 mL, 0.37 mmol) was added followed by water. The layers were separated and the aqueous layer was extracted one more time with ethyl acetate. The combined organic layers were dried over magnesium sulfate and concentrated to afford 6-[4-({[3-{[(2,6-dichlorophenyl)amino]methyl}-5-(1-methylethyl)-4-isoxazolyl]methyl}oxy)phenyl]-2-quinolinecarboxylic acid (8 mg, 100%). 1H-NMR (400 MHz, CDCl3) δ 8.46 (d, J=9 Hz, 1H), 8.31-8.24 (m, 2H), 8.11-8.07 (m, 2H), 7.69 (d, J=9 Hz, 2H), 7.25-7.20 (m, 2H), 7.07 (d, J=9 Hz, 2H), 6.84-6.80 (m, 1H), 4.96 (s, 2H), 4.60 (s, 2H), 3.24 (septet, J=7 Hz, 1H), 1.36 (d, J=7 Hz, 6H). HRMS (ESI) C30H25Cl2N3O4 calculated: 562.1300 (M+H)+, found: 562.1292 (M+H)+.
