To a solution of crude [4,4,4-Trifluoro-1-(2-{5-[4′-(2-pyrrolidin-2-yl-3H-imidazol-4-yl)-biphenyl-4-yl]-1H-imidazol-2-yl}-pyrrolidine-1-carbonyl)-butyl]-carbamic acid methyl ester (115 mg, 0.18 mmol) in dimethylformamide (0.5 mL) was added a solution of 5,5,5-Trifluoro-2-methoxycarbonylamino-pentanoic acid (44 mg, 0.19 mmol) and HATU (72 mg, 0.19 mmol) in dimethylformamide (0.5 mL). Diisopropylethylamine (65 μL, 0.37 mmol) was then added and the reaction was stirred at room temperature for 16 hours. The solution was concentrated and purified by preparative reverse phase HPLC (Gemini, 15 to 50% ACN/H2O+0.1% HCO2H) to yield (4,4,4-Trifluoro-1-{2-[5-(4′-{2-[1-(5,5,5-trifluoro-2-methoxycarbonylamino-pentanoyl)-pyrrolidin-2-yl]-3H-imidazol-4-yl}-biphenyl-4-yl)-1H-imidazol-2-yl]-pyrrolidine-1-carbonyl}-butyl)-carbamic acid methyl ester (35 mg, 23%). LCMS-ESI+: calculated for C40H44F6N8O6: 846.82; observed [M+1]+: 847.34.
