Under nitrogen atmosphere, a mixture of 3-methoxy-2,2-dimethylpropionic acid 5-[[3-(2-acetoxyethoxy)-2-fluoro-5-methoxyphenyl]-(4-{amino[benzoylimino]methyl}phenylamino)methyl]-2-pyrimidin-2-yl-2H-[1,2,4]triazol-3-yloxymethyl ester (184 mg), methanol (10 mL), and acetic acid (1 mL) was stirred at 40° C. for 15 hours. Under reduced pressure, the solvent in the mixture was distilled off. The residue obtained was purified by reverse phase silica gel column chromatography (mixed solvent of acetonitrile-water, containing 0.1% of acetic acid) to obtain the captioned compound (146 mg).
