To a mixture of [1-amino-1-[4-({(5-chloromethoxy-1-pyrimidin-2-yl-1H-[1,2,4]triazol-3-yl)-[2-fluoro-3-(2-hydroxyethoxy)-5-methoxyphenyl]methyl}amino)phenyl]methylidene]carbamic acid 2,2-dimethylpropyl ester (Example 2b, 120 mg), potassium hydrogen carbonate (131 mg), and DMF (16 mL), sodium iodide (140 mg) and cyclohexanecarboxylic acid (163 mg) were added, and the resulting mixture was stirred at 45° C. overnight. After cooling the reaction mixture to room temperature, ice and saturated aqueous ammonium chloride solution were added thereto, and the resulting mixture was extracted three times with a mixture of THF and ethyl acetate. The organic layer was collected, washed with saturated aqueous ammonium chloride solution, and dried over anhydrous magnesium sulfate. The resulting mixture was filtered, and the filtrate obtained was concentrated under reduced pressure. The residue obtained was purified by NAM silica gel column chromatography (mixed solvent of methanol-ethyl acetate) to obtain the captioned compound (123 mg).
