実験手順

A solution of methyl 3-methyl-6-[(1-methylethyl)thio]-7-(methyloxy)-2-[3-(trifluoromethyl)phenyl]-4-quinolinecarboxylate (5.5 g, 4.04 mmol) and 3-chloroperoxybenzoic acid (1.819 g, 8.12 mmol) in dichloromethane (50 mL) was stirred overnight. Saturated aqueous NaHCO3 and Na2S2O3 were added slowly, and the mixture was stirred for 30 min before it was extracted with methylene chloride (three times). The combined organic extracts were washed with brine (two times), dried over Na2SO4, filtered, and concentrated in vacuo. The residue was purified via column chromatography (ISCO, 0-15% ethyl acetate/methylene chloride) to afford methyl 3-methyl-6-[(1-methylethyl)sulfonyl]-7-(methyloxy)-2-[3-(trifluoromethyl)phenyl]-4-quinolinecarboxylate (1.76 g, 91% yield). 1H NMR (400 MHz, DMSO-d6) 68.24 (s, 1H), 7.99-8.05 (m, 2H), 7.92 (d, J=8.03 Hz, 1H), 7.76-7.84 (m, 2H), 4.09 (s, 6H), 3.83 (quin, J=6.78 Hz, 1H), 2.37 (s, 3H), 1.21 (s, 3H), 1.20 (s, 3H); MS (m/z) 482.1 (M+H+).
