Procedure

To a mixture of Acetic acid 2-{3-[(R)-(4-carbamimidoylphenylamino)-(5-isopropoxycarbonyloxymethoxy-1-pyrimidin-2-yl-1H-[1,2,4]triazol-3-yl)methyl]-2-fluoro-5-methoxyphenoxy}ethyl ester acetic acid salt (23 mg) obtained in Example 67a and DMF (1 ml), carbonic acid isobutyl ester 4-nitrophenyl ester [CAS No. 112240-73-0] (10 mg) and triethylamine (50 μL) were added, and the resulting mixture was stirred at room temperature for 64 h. Ethyl acetate and water were added to the mixture, and the organic layer was collected. The organic layer was sequentially washed with water and with saturated aqueous sodium chloride solution, and dried over anhydrous magnesium sulfate. The desiccant was filtered off, and the filtrate obtained was concentrated under reduced pressure. The residue obtained was purified by silica gel column chromatography (mixed solvent of heptane-ethyl acetate) to obtain the captioned compound (14.99 mg).
