Versuchsvorschrift

To a solution of ethyl 6-[4-({[3-{[(2,6-dichlorophenyl)thio]methyl}-5-(1-methylethyl)-4-isoxazolyl]methyl}oxy)phenyl]-2-quinolinecarboxylate (20 mg, 0.033 mmol) in dichloromethane (1 mL) at 0° C. was added meta-chloroperoxybenzoic acid (15 mg, 0.066 mmol). The mixture was stirred at 0° C. for approximately 30 minutes. Aqueous sodium bicarbonate was added and the mixture was extracted twice with dichloromethane. The combined organic layers were dried over magnesium sulfate, adsorbed onto silica gel and purified by chromatography (silica gel, 0-100% ethyl acetate in hexanes gradient elution) to afford ethyl 6-[4-({[3-{[(2,6-dichlorophenyl)sulfinyl]methyl}-5-(1-methylethyl)-4-isoxazolyl]methyl}oxy)phenyl]-2-quinolinecarboxylate (12 mg, 0.019 mmol, 57%). 1H-NMR (400 MHz, CDCl3) δ 8.39 (d, J=9 Hz, 1H), 8.23 (d, J=9 Hz, 2H), 8.05-8.03 (m, 2H), 7.68 (d, J=9 Hz, 2H), 7.31 (s, 3H), 7.07 (d, J=9 Hz, 2H), 5.10-4.90 (m, 2H), 4.80-4.58 (m, 2H), 3.22 (septet, J=7 Hz, 1H), 1.32 (d, J=7 Hz, 6H). LRMS m/z 623 (M+H)+.
