Procedure

800 mg (1.37 mmol) of 6,8-difluoro-2-(3-fluoro-4-pivaloylaminophenyl)-7-methanesulfonyloxymethyl-5-pivaloylamino-4H-1-benzopyran-4-one obtained in Example 120 (1) was dissolved in 10 mL of dimethylformamide, 558 mg (6.85 mmol) of dimethylamine hydrochloride and 945 mg (6.85 mmol) of potassium carbonate were added and the mixture was stirred at room temperature for 45 minutes. Water was added to the reaction solution and the mixture was extracted once with ethyl acetate. The organic layer was washed once with water and once with an aqueous saturated solution of sodium chloride, and dried over anhydrous sodium sulfate, and the solvent was distilled off under reduced pressure to give 727 mg of 7-dimethylaminomethyl-6,8-difluoro-2-(3-fluoro-4-pivaloylaminophenyl)-5-pivaloylamino-4H-1-benzopyran-4-one (yield: 100%).
