To a mixture of 2,2-dimethylmalonic acid 5-{(4-{amino[benzoylimino]methyl}phenylamino)-[2-fluoro-3-(2-hydroxyethoxy)-5-methoxyphenyl]methyl}-2-pyrimidin-2-yl-2H-[1,2,4]triazol-3-yloxymethyl ester 2,2-dimethylpropyl ester (500 mg) and methanol (4 mL), acetic acid (1 mL) was added, and the resulting mixture was stirred at 40° C. for 4 hours. The mixture was concentrated under reduced pressure, and 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 (430 mg).
