Reaction Steps

0.4 g (1.1 mmol) of 3-(4-chloro-2-hydroxymethylbenzofuran-7-yl)-1-methyl-6-trifluoromethyluracil and 0.13 g (1.2 mmol) of triethylamine were dissolved in 20 ml of tetrahydrofuran, and 0.1 g (1.2 mmol) of acetyl chloride was dropwise added thereto under cooling with ice. After completion of the reaction, the reaction solution was poured into water and washed with ethyl acetate. The organic layer was washed sequentially with a 10% hydrochloric acid aqueous solution, 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 0.2 g (yield: 45.5%) of the desired product as white solid. Melting point: 135-138° C.
