Versuchsvorschrift
To 22 mg of (2R)-N-{((3S)-1-ethyl-3-piperidyl)methyl}-1-{(2S,4R)-4-hydroxy-1-(3,3,3-triphenylpropanoyl)pyrrolidin-2-yl}carbonylpyrrolidine-2-carboxamide, 1 ml of ethyl iodide was added at room temperature, followed by 2 hours' stirring at 70° C. The resultant reaction liquid was diluted with chloroform and the solvent was distilled off under reduced pressure. The resultant residue was dissolved in ultrapure water 0.6 ml/methanol 0.1 ml and the solution was developed on reversed phase medium-pressure liquid chromatograpy [ODS-AQ 120-S50 (YMC)]. Purification and anion exchange were conducted by pouring 20 ml of saturated brine, washing with 150 ml of ultrapure water and eluting the title compound with methanol/water=1/1, to provide 21 mg of the title compound as a white solid.
