실험 절차

To (E)-3,4-difluoro-2-(2-fluoro-4-iodo-phenylamino)-N-(2-hydroxy-ethoxy)-5-[(3-methylcarbamoyl-propoxyimino)-methyl]-benzamide (50 mg, 0.084 mmol) obtained in Step C was added dichloromethane (6 ml). The mixture was stirred at room temperature, and borane-pyridine complex (67 μl, 0.673 mmol) and dichloroacetic acid (55 μl, 0.673 mmol) were added thereto. After stirring for 14 hours, the reaction mixture was diluted with ethyl acetate, and washed with purified water and saturated aqueous sodium chloride. The organic layer was dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography to give 3,4-difluoro-2-(2-fluoro-4-iodo-phenylamino)-N-(2-hydroxy-ethoxy)-5-[(3-methylcarbamoyl-propoxyamino)-methyl]-benzamide (Compound C-21, 32 mg, 65% yield).
