To a solution of 2-[5-(4-{6-[2-(1-Benzyloxycarbonyl-pyrrolidin-2-yl)-3H-imidazol-4-yl]-naphthalen-2-yl}-phenyl)-1H-imidazol-2-yl]-4,4-difluoro-pyrrolidine-1-carboxylic acid tert-butyl ester (0.25 g, 0.34 mmol) in CH2Cl2 (3.5 mL) and MeOH (0.25 mL) was added HCl (in dioxanes, 4 M, 1.7 mL, 7.8 mmol). The solution was stirred at room temperature for 2.5 h and concentrated to dryness. The resulting solid was slurried in CH2Cl2 (3 mL) and DMF (1 mL). Methoxycarbonylamino-(tetrahydro-pyran-4-yl)-acetic acid (0.11 g, 0.50 mmol), HATU (0.15 g, 0.40 mmol), and DIPEA (0.3 mL, 1.7 mmol) were added. The resulting solution was stirred at room temperature for 18 h. The solution was diluted with CH2Cl2 and washed with saturated sodium bicarbonate. The organic layer was dried over Na2SO4 and concentrated. The crude oil was purified by column chromatography (SiO2, 2→20% MeOH in CH2Cl2), followed by preparative HPLC (Gemini, 15→50% MeCN in H2O (0.1% TFA)) to provide 2-(5-{6-[4-(2-{4,4-Difluoro-1-[2-methoxycarbonylamino-2-(tetrahydro-pyran-4-yl)-acetyl]-pyrrolidin-2-yl}-3H-imidazol-4-yl)-phenyl]-naphthalen-2-yl}-1H-imidazol-2-yl)-pyrrolidine-1-carboxylic acid benzyl ester (0.13 g, 46%). LCMS-ESI+: calc'd for C47H47F2N7O6: 843.36 (M+); Found: 844.78 (M+H+).
