Participants

Reaction Steps

To a stirring solution of 3-[2-(methylsulfinyl)ethyl]-2-phenyl-N-[(1S)-1-phenylpropyl]quinoline-4-carboxamide (12) (60 mg, 0.13 mmol) in CH2Cl2 at 0° C. was added MCPBA (70-75%, 36 mg, 0.16 mol). The cooling bath was removed and reaction stirred for 2 h, then sodium thiosulfate (1.2 eq.) and H2O (1 mL) were added and suspension stirred until all solids had dissolved. Aqueous 1 N NaOH (1 mL) and CH2Cl2 (2 mL) were then added, the layers shaken together, separated, the organics dried over Na2SO4, filtered, and concentrated under reduced pressure. The residue was purified by silica gel chromatography (5-20% EtOAc/CH2Cl2) to give the desired product (40 mg, 65% yield) as a solid. 1H NMR (300 MHz, CDCl3, 52° C.) δ 8.12 (d, J=8.2 Hz, 1H), 7.78-7.65 (m, 2H), 7.56-7.26 (m, 11H), 6.31 (d, J=7.7 Hz, 1H), 5.23 (q, J=7.6 Hz, 1H), 3.36-2.88 (m, 4H), 2.45-2.34 (m, 3H), 2.16-1.88 (m, 2H), 1.04 (t, J=7.4 Hz, 3H); HRMS m/z 473.1878, calcd 473.1899.
