Mode opératoire

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 (125 mg, 0.20 mmol) in dimethylformamide (0.6 mL) was added a solution of 2-methoxycarbonylamino-3-methyl-butyric acid (38 mg, 0.22 mmol) and HATU (82 mg, 0.22 mmol) in dimethylformamide (0.6 mL). Diisopropylethylamine (70 μL, 0.40 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-(2-methoxycarbonylamino-3-methyl-butyryl)-pyrrolidin-2-yl]-3H-imidazol-4-yl}-biphenyl-4-yl)-1H-imidazol-2-yl]-pyrrolidine-1-carbonyl}-butyl)-carbamic acid methyl ester (73 mg, 47%).
