Reaction Steps

0.87 g of m-chloroperbenzoic acid (purity: 70%, 3.54 mmoles) was added, with ice-cooling, to a solution of 0.85 g (2.53 mmoles) of 3-(5-chloro-1-methyl-3-phenyl-1H-pyrazol-4-ylmethylthio)-5,5-dimethyl-2-isoxazoline dissolved in 30 ml of chloroform. The mixture was stirred at room temperature for 1 hour to give rise to a reaction. After the completion of the reaction, the reaction mixture was poured into water, followed by extraction with chloroform. The resulting organic layer was washed with an aqueous sodium hydrogensulfite solution, an aqueous sodium hydrogencarbonate solution and an aqueous sodium chloride solution in this order and then dried over anhydrous magnesium sulfate. The resulting solution was subjected to vacuum distillation to remove the solvent contained therein. The residue was purified by silica gel column chromatography (developing solvent: hexane-ethyl acetate mixed solvent) to obtain 0.48 g (yield: 53.9%) of 3-(5-chloro-1-methyl-3-phenyl-1H-pyrazol-4-ylmethylsulfinyl)-5,5-dimethyl-2-isoxazoline as a transparent viscous substance.
