To a solution of 2.000 g 4-((S)-4-tert-Butoxycarbonyl-2-{[5-((S)-1-carboxy-ethoxy)-1-phenyl-1H-pyrazole-3-carbonyl]-amino}-butyryl)-piperazine-1-carboxylic acid ethyl ester in 15 ml DMF were added 0.509 g HOBt, 1.37 ml DIPEA and 0.804 g L-proline benzyl ester hydrochloride at RT. Then 0.637 g EDC was added portionwise and the suspension stirred at RT for 12 h. The reaction mixture was diluted with ethyl acetate and subsequently extracted with aqueous LiCl (4% w/w), aqueous NaHCO3 and brine. The organic layer was dried over MgSO4 and the solvent was removed under reduced pressure. The crude product thus obtained was used in the subsequent reaction. Yield: 2.177 g.
