実験手順

506 mg (1.40 mmol) of the above 2-(4-acetylamino-3-fluorophenyl)-5-amino-6,8-difluoro-7-methyl-4H-1-benzopyran-4-one was dissolved in 30 mL of dimethylformamide under argon atmosphere, 60 mg (1.5 mmol) of sodium hydride (60% oil dispersion) and 0.28 mL (2.8 mmol) of 1-iodopropane were added thereto under ice-cooling and the mixture was stirred at room temperature for 6 hours. Water was added to the reaction solution and the mixture was extracted twice 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. The solvent was distilled off under reduced pressure and the residue was purified by silica gel column chromatography (chloroform) to give 315 mg of 2-[4-[N-acetyl-N-(1-propyl)amino]-3-fluorophenyl]-5-amino-6,8-difluoro-7-methyl-4H-1-benzopyran-4-one (yield: 56%).
