To a mixture of 2,2-dimethylmalonic acid 5-{(4-carbamimidoylphenylamino)-[2-fluoro-3-(2-hydroxyethoxy)-5-metho xyphenyl]methyl}-2-pyrimidin-2-yl-2H-[1,2,4]triazol-3-yloxymethyl ester 2,2-dimethylpropyl ester acetate (270 mg), carbonic acid 2,2-dimethylbutyl ester 4-nitrophenyl ester (141 mg), and THF (10 mL), triethylamine (0.17 mL) was added, and the resulting mixture was stirred at room temperature for 26 hours. Acetic acid (0.3 mL) was added to the reaction solution, and the resulting mixture 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.
