Procedure

To a solution of (1R,3S,5R)-tert-butyl-3-(9-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1,11-dihydroisochromeno[4′,3′:6,7]naphtho[1,2-d]imidazol-2-yl)-2-azabicyclo[3.1.0]hexane-2-carboxylate (213 mg, 0.37 mmol), methyl (S)-1-((2S,4S)-2-(5-bromo-1H-imidazol-2-yl)-4-(methoxymethyl)pyrrolidin-1-yl)-3-methyl-1-oxobutan-2-ylcarbamate (142 mg, 0.31 mmol), tetrakis(triphenylphosphine) palladium(0) (35 mg, 0.03 mmol) and dichloro[1,1′-bis(diphenylphosphino)ferrocene]palladium(II) (22 mg, 0.03 mmol) in a mixture of 1,4-dioxane (3.0 mL) and dimethylsulfoxide (3.0 mL) was added a solution of potassium carbonate (2M in water, 0.46 mL, 0.9 mmol). The resulting mixture was degassed and then heated to 95° C. under argon for 7 hours. After cooling to room temperature, the reaction was diluted with ethyl acetate. The organics were washed with water and brine, dried (Na2SO4), and concentrated. The crude residue was purified by flash chromatography to (1R,3S,5R)-tert-butyl 3-(9-(2-((S)-1-((S)-2-(methoxycarbonylamino)-3-methylbutanoyl)-4-methoxymethylpyrrolidin-2-yl)-1H-imidazol-5-yl)-1,11-dihydroisochromeno[4′,3′:6,7]naphtho[1,2-d]imidazol-2-yl)-2-azabicyclo[3.1.0]hexane-2-carboxylate (101 mg, 42%).
