Versuchsvorschrift

3.74 g Z-D-Pro-OH (15 mmol, BACHEM) and 8.25 g H-Val-MeVal-Pro-Pro-NHBn×HCl (15 mmol) were dissolved in 80 ml dry DMF. After cooling to 0° C., 2.4 g DEPCN (2.25 ml, 15 mmol) and 4.2 ml triethylamine (30 mmol) were added. The reaction mixture was stirred at 0° C. for several hours and room temperature overnight, then the DMF was evaporated under reduced pressure. The residue was diluted with ethyl acetate and thoroughly washed with dilute aqueous HCl (pH 2), water, dilute aqueous NaOH (pH 9–10), and water. The organic phase was dried over sodium sulfate and evaporated to dryness to yield 9.2 g of the desired protected pentapeptide.
