Procedure
2 g (5.7 mmol) of N-(benzylthio)acetyl-4-chloro-anthranilic acid methyl ester and 3.66 g (17.1 mmol) of sodium metaperiodate are dissolved in 12 ml of water and 48 ml of acetone and the resulting solution is stirred at reflux for 6 hours. The reaction mixture is allowed to cool, filtered and concentrated by evaporation. Chromatography of the crude product on silica gel with hexane/ethyl acetate yields N-(benzylsulfinyl)acetyl-4-chloro-anthranilic acid methyl ester in the form of a yellow oil interspersed with crystals.
