Reaction Steps

To a solution of [2-Oxo-1-(tetrahydro-pyran-4-yl)-2-(3-{5-[4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-1H-imidazol-2-yl}-2-azabicyclo[2.2.1]hept-2-yl)-ethyl]-carbamic acid methyl ester (0.24 g, 0.42 mmol) in DME (2.5 mL) was added 2-[5-(6-Bromo-naphthalen-2-yl)-1H-imidazol-2-yl]-pyrrolidine-1-carboxylic acid tert-butyl ester (0.19 g, 0.43 mmol), Tetrakis(triphenylphosphine)Palladium (0.03 g, 0.02 mmol) and aqueous potassium phosphate (2 M, 0.65 mL, 1.3 mmol). The solution was degassed with argon for 15 min and heated to 80° C. for 18 h with stirring. The solution was cooled and concentrated. The crude oil was purified by column chromatography (SiO2, 30-100% EtOAc (10% MeOH) in Hexanes to 50% MeOH in EtOAc) to provide 2-(5-{6-[4-(2-{2-[2-Methoxycarbonylamino-2-(tetrahydro-pyran-4-yl)-acetyl]-2-azabicyclo[2.2.1]hept-3-yl}-3H-imidazol-4-yl)-phenyl]-naphthalen-2-yl}-1H-imidazol-2-yl)-pyrrolidine-1-carboxylic acid tert-butyl ester (0.26 g, 76%). LCMS-ESI+: calc'd for C46H53N7O6: 799.41 (M+); Found: 800.4 (M+H+).
