Procedure
Methyl(1S)-chloromethyl-5-hydroxy-3-[5-(7-methoxybenzofuran-2-ylcarbonyl)amino-1H-indol-2-ylcarbonyl]-7-trifluoromethyl-1,2,3,6-tetrahydropyrrolo[3,2-e]indole-8-carboxylate (10.2 mg, 15 μmol) and 4-nitrophenyl chloroformate (7.6 mg, 38 μmol) were dissolved in 1 mL of tetrahydrofuran, and thereto triethylamine (4.2 μL, 30 μmol) was added dropwise with ice cooling. After one hour, (2S)-pyrrolidine-2-methanol (4.4 μL, 45 μmol) was added dropwise. The mixture was stirred for two hours, and stirred further for two hours at room temperature. The reaction mixture was poured into 3 mL of saturated aqueous sodium chloride solution and 3 mL of ethyl acetate for extraction. The extracted matter was dried over anhydrous sodium sulfate, and the solvent was evaporated off. The resulting residue was purified by silica gel column chromatography (hexane:acetone=1:1) to obtain 8.5 mg (70%) of methyl (1S)-chloromethyl-5-{[(2S)-hydroxymethylpyrrolidin-1-ylcarbonyl]oxy}-3-[5-(7-methoxybenzofuran-2-ylcarbonyl)amino-1H-indol-2-ylcarbonyl]-7-trifluoromethyl-1,2,3,6-tetrahydropyrrolo[3,2-e]indole-8-carboxylate.
