Procedure
0.21 g (0.5 mmol) of 3-(2-carboxy-4-chloro-6-fluorobenzofuran-7-yl)-1-methyl-6-trifluoromethyluracil and 0.16 g (1.1 mmol) of potassium carbonate were suspended in 10 ml of N,N-dimethylformamide, and 0.15 g (1.1 mmol) of methyl iodide was added thereto at room temperature, followed by stirring at room temperature for 3 hours. After completion of the reaction, the reaction solution was poured into water and extracted with ethyl acetate. The organic layer was washed sequentially with water and a saturated sodium chloride aqueous solution, and then dried over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure. Then, the obtained residue was purified by silica gel column chromatography to obtain 0.21 g (yield: 96.8%) of the desired product as yellowish brown crystals. Melting point: 194-196° C.
