Procedure

To a solution of 2-{5-[6-(4-{2-[1-(2-Methoxycarbonylamino-2-phenyl-acetyl)-pyrrolidin-2-yl]-3H-imidazol-4-yl}-phenyl)-naphthalen-2-yl]-1H-imidazol-2-yl}-pyrrolidine-1-carboxylic acid tert-butyl ester (0.12 g, 0.15 mmol) in CH2Cl2 (1.5 mL) and MeOH (0.2 mL) was added HCl (in dioxanes, 4 M, 0.75 mL, 3.0 mmol). The solution was stirred at room temperature for 2 h and concentrated to dryness. The resulting solid was dissolved in DMF (1.5 mL). 2-Methoxycarbonylamino-3-(tetrahydro-pyran-4-yl)-propionic acid (0.05 g, 0.22 mmol), HATU (0.07 g, 0.19 mmol) and DIPEA (0.13 mL, 0.74 mmol) were added. The resulting solution was stirred at room temperature for 18 h. The solution was purified twice by preparative HPLC (Gemini, 15→40% MeCN in H2O (0.1% TFA)) and lyophilized to provide [2-(2-{5-[6-(4-{2-[1-(2-Methoxycarbonylamino-2-phenyl-acetyl)-pyrrolidin-2-yl]-3H-imidazol-4-yl}-phenyl)-naphthalen-2-yl]-1H-imidazol-2-yl}-pyrrolidin-1-yl)-2-oxo-1-(tetrahydro-pyran-4-ylmethyl)-ethyl]-carbamic acid methyl ester (0.024 g, 18%). LCMS-ESI+: calc'd for C50H54N8O7: 878.41 (M+); Found: 879.97 (M+H+).
