Procedure
99 mg of isopropyl 5-acetoxy-4-isopropoxycarbonyl-5-[N-[(1RS,2RS)-1-methyl-2-(4-nitrophenyl)-3-{5-(phenylcarbamoyl)-2-furyl}propyl]-N-(2-naphthylmethyl)carbamoyl]pentanoate obtained by subjecting N-{(1RS,2RS)-1-methyl-2-(4-nitrophenyl)3-{5-(phenylcarbamoyl)-2-furyl}propyl]-2-naphthylmethylamine obtained in Example 23(1) and 2,4-diisopropyl 1-acetoxy-1,2,4-butanetricarboxylate obtained in Reference Example 5 to a condensation reaction in accordance with the method of Example 24(1), was dissolved in 3 ml of isopropanol, and 9.8 mg of sodium isopropoxide was added thereto, followed by stirring at room temperature for one hour. The reaction solution was poured into water and extracted with ethyl acetate. Then, the organic layer was dried over anhydrous magnesium sulfate. The drying agent was filtered off, and then, the solvent was distilled off under reduced pressure. The residue was purified by silica gel column chromatography (hexane/ethyl acetate=2/1) to obtain 43 mg (yield: 45%) of the above-identified compound.
