Versuchsvorschrift

[1-(2-{5-[6-(4-{2-[1-(2-Amino-2-phenyl-acetyl)-pyrrolidin-2-yl]-3H-imidazol-4-yl}-phenyl)-naphthalen-2-yl]-1H-imidazol-2-yl}-pyrrolidine-1-carbonyl)-2-methyl-propyl]-carbamic acid methyl ester (0.05 g, 0.057 mmol) was suspended in THF (0.572 mL). Upon addition of DIPEA (0.050 mL, 0.286 mmol), the slurry partially clarified. Propionyl chloride (0.005 mL, 0.057 mmol) was added at room temperature and the reaction was allowed to stir at room temperature overnight. Upon completion, the reaction was quenched with a small amount of formic acid and purified by reverse phase HPLC (10-45% acetonitrile:water; 0.1% formic acid modifier), and lyophilized giving [2-Methyl-1-(2-{5-[6-(4-{2-[1-(2-phenyl-2-propionylamino-acetyl)-pyrrolidin-2-yl]-3H-imidazol-4-yl}-phenyl)-naphthalen-2-yl]-1H-imidazol-2-yl}-pyrrolidine-1-carbonyl)-propyl]-carbamic acid methyl ester (0.008 g, 17%) as a white solid. LCMS-ESI+: calc'd for C48H52N8O5: 820.41 (M+); Found: 821.51 (M+H+).
