3-Butyryl-4-(2-isopropylphenylamino)-8-(2-methylthioethoxy)quinoline (0.22 g, 0.52 mmol) was dissolved in methylene chloride (15 ml) and added to a mixture of 0.093 g NaHCO3 in 15 ml H2O. A solution of 71% m-CPBA (0.12 g, 0.50 mmol) in 7 ml methylene chloride was added dropwise at 4° C. The solution was stirred for one hour at this temperature. The reaction mixture was washed with a saturated sodium bicarbonate solution. The organic layer was dried over Na2SO4 and evaporated. Chromatography with methylene chloride:methanol 10:1 as eluent gave 0.130 g (57%) of the desired product.
