실험 절차

To a solution of methyl 6-[4-({[5-cyclobutyl-3-(2,6-dichlorophenyl)-4-isoxazolyl]methyl}oxy)phenyl]-1-naphthalenecarboxylate (65 mg, 0.116 mmol) in a 2:1 mixture of tetrahydrofuran and methanol (1.5 mL) was added 1N sodium hydroxide (0.175 mL, 0.175 mmol). The solution was heated in a microwave reactor at 120° C. for 500 seconds. The solution was concentrated and water was added followed by 0.175 mL of 1N HCl. The solution was extracted twice with ethyl acetate. The combined organic phases were washed one time with brine and concentrated. Ether was added and the solution was again concentrated to dryness to afford the title compound as a white solid (56 mg, 89%). 1H-NMR (DMSO-d . 13.14 (s, 1H), 8.88 (d, J=9 Hz, 1H), 8.20-8.16 (m, 2H), 8.09 (d, J=9 Hz, 1H), 7.90 (d, J=9 Hz, 1H), 7.69-7.49 (m, 6H), 6.90 (d, J=9 Hz, 2H), 4.83 (s, 2H), 4.00 (quintet, J=9 Hz, 1H), 2.43-2.34 (m, 4H), 2.10-1.92 (m, 2H). HRMS C31H23Cl2NO4 m/z 544.10769 (M+H)+Cal; 544.10747 (M+H)+Obs.
