実験手順
1.09 g of (2S,4S)-4-(4-methoxybenzylthio)-1-methylpyrrolidine-2-carboxylic acid were suspended in 30 ml of dry acetonitrile, and 691 mg of N,N'-carbonyldiimidazole were added to this suspension, after which the mixture was stirred at 40° C. for 1 hour. At the end of the time, the reaction mixture was cooled with ice, and 2.98 g of (3S)-3-[2-[2,3-bis(4-nitrobenzyloxycarbonyl)guanidino]acetylamino]pyrrolidine trifluoroacetate in 30 ml of dry acetonitrile and 1.7 ml of diisopropylethylamine were added to the mixture, which was then stirred at room temperature overnight. At the end of this time, the reaction mixture was diluted with ethyl acetate and washed with water and brine. The ethyl acetate solution was dried over anhydrous sodium sulfate and then concentrated by evaporation under reduced pressure. The resulting residue was subjected to silica gel column chromatography, eluted with 10% and 20% methanol-ethyl acetate. The fraction containing the desired compound was concentrated by evaporation under reduced pressure to obtain 2.99 g of (2S,4S)-2-[(3S)-3-[2-[2,3-bis(4-nitrobenzyloxycarbonyl)guanidino]acetylamino]pyrrolidin-1-ylcarbonyl]-4-(4-methoxybenzylthio)-1-methylpyrrolidine, as a powder.
