To a mixture of N-[1-amino-1-(4-{[[2-fluoro-3-(2-hydroxyethoxy)-5-methoxyphenyl]-(5-oxo-1-pyrimidin-2-yl-4,5-dihydro-1H-[1,2,4]triazol-3-yl)methyl]amino}phenyl)methylidene]benzamide (Example 1a, 1.0 g) and DMF (20 mL), potassium hydrogen carbonate (1.67 g) and 1-chloroethyl cyclohexyl carbonate (2.76 g) were added, and the resulting mixture was stirred at 55° C. for 26 hours. The reaction solution 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 (680 mg).
