To a mixture of 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)benzamidine acetic acid salt [CAS No. 951803-95-5] (613 mg) and DMF (5 mL), benzoic acid 4-nitrophenyl ester [CAS No. 959-22-8] (280 mg) and triethylamine (0.2 mL) were added and the resulting mixture was stirred at 50° C. overnight. Acetic acid was added to the reaction solution, and the solvent was evaporated 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 (492 mg).
