Versuchsvorschrift

Under nitrogen atmosphere, a mixture of acetic acid 2-{3-[(R)-{4-[amino(2-methylallyloxycarbonylimino)methyl]phenylamino}-(5-oxo-1-pyrimidin-2-yl-4,5-dihydro-1H-[1,2,4]-triazol-3-yl)methyl]-2-fluoro-5-methoxyphenoxy}ethyl ester (Example 45, 250 mg), carbonic acid chloromethyl ester isopropyl ester [CAS No. 35180-01-9] (121 mg), rubidium carbonate (73.2 mg) and DMA (10 mL) was stirred at 85° C. for 90 minutes. After cooling the mixture to room temperature, ethyl acetate and water were added thereto. The organic layer was collected, the aqueous layer was reextracted with ethyl acetate, and all the organic layers were combined. 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-methanol) to obtain the acetic acid 2-{3-[(R)-(4-{amino[2-methylallyloxycarbonylimino]methyl}phenylamino)-(5-isopropoxycarbonyloxymethoxy-1-pyrimidin-2-yl-1H-[1,2,4]triazol-3-yl)methyl]-2-fluoro-5-methoxyphenoxyl}ethyl ester as a solid.
