Procedure

To a solution 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 (0.04 g, 0.05 mmol) and (5)-Methoxycarbonylamino-(2-methoxy-phenyl)-acetic acid (0.02 g, 0.08 mmol, 1.5 equiv.) in CH2Cl2 (0.5 mL) was added K3PO4 (0.03 g, 0.15 mmol, 3 equiv.). The slurry was cooled to 0° C. and COMU (0.03 g, 0.06 mmol, 1.25 equiv.) and the reaction was stirred at 0° C. for 1 hour. The slurry was diluted with CH2Cl2 and filtered. The filtrate was concentrated and the crude product 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-[2-Methoxycarbonylamino-2-(2-methoxy-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 (0.02 g, 50%) as a white powder. LCMS-ESI+: calc'd for C48H52N8O7: 852.4 (M+).
