Versuchsvorschrift

To a solution of 3,4-difluoro-2-(2-fluoro-4-iodo-phenylamino)-N-(2-hydroxy-ethoxy)-5-[(2-methanesulfinyl-ethoxyamino)-methyl]-benzamide (10 mg, 0.017 mmol) obtained in Example 10 in a mixed solvent of methanol (1.8 mL) and water (0.2 mL) was added sodium metaperiodate (6 mg, 0.026 mmol) at room temperature, and the mixture was stirred for 17 hours. After completion of the reaction, the reaction mixture was extracted with ethyl acetate, and the organic layer was washed sequentially with water and saturated brine, dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The resultant residue was purified by preparative TLC (No. 5744, Merck, 5% methanol/methylene chloride as a developing solvent) to give 3,4-difluoro-2-(2-fluoro-4-iodo-phenylamino)-N-(2-hydroxy-ethoxy)-5-[(2-methanesulfonyl-ethoxyamino)-methyl]-benzamide (1.3 mg, 13%) as an off-white solid.
