Versuchsvorschrift

Triethylamine (33 μL), 1-hydroxybenzotriazole (30 mg), and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (46 mg) were added to a suspension of the crude N-tert-butoxycarbonyl-trans-4-(N,N-dimethylglycylamino)-L-proline (B) and trans-4-((R)-2-hydroxy-4-phenylbutyrylamino)-L-proline 3-quinolylamide (Compound D101 (H), 84 mg) in dichloromethane (5 mL) at 0° C. After stirring at 0° C. for 30 min and at room temperature for 14 hr, the solvent was removed in vacuo. The residue was diluted with saturated sodium hydrogen carbonate and extracted with chloroform-methanol (10:1,v/v). The organic layer was washed with brine, dried over anhydrous sodium sulfate, and evaporated in vacuo. The residue was purified by preparative thin layer chromatography (Whatman, PLK5F Silica Gel 150, chloroform:methanol=10:1, v/v) to afford the title compound (76 mg) as a colorless glassy solid: mass spectrum (EI+) m/e 715 (M+); (FAB+) m/e 716 (M+1).
