Procedure

To a slurry of {2-Methyl-1-[2-(5-{6-[4-(2-pyrrolidin-2-yl-3H-imidazol-4-yl)-phenyl]-naphthalen-2-yl}-1H-imidazol-2-yl)-pyrrolidine-1-carbonyl]-propyl}-carbamic acid methyl ester (0.045 g, 0.06 mmol) and (S)-methoxycarbonylamino-phenyl-acetic acid (0.02 g, 0.09 mmol, 1.5 equiv.) in CH2Cl2 (0.6 mL) was added HATU (0.03 g, 0.08, 1.25 equiv.) and K3PO4 (0.05 g, 0.22 mmol, 3 equiv.). The reaction mixture was stirred at room temperature for 18 hours and diluted with CH2Cl2. The salts were filtered and the filtrate was concentrated. The crude oil was purified by preparative HPLC (Gemini, 15→40% MeCN in H2O (0.1% formic acid)) and lyophilized to provide [1-(2-{5-[6-(4-{2-[1-(2S)-(2-Methoxycarbonylamino-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 (0.03 g, 65%) as a white powder.
