実験手順

To a solution of [(2S)-3-methyl-1-{(2S,5S)-2-methyl-5-[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]pyrrolidin-1-yl}-1-oxobutan-2-yl]carbamate (269 mg, 0.42 mmol), (2S,4S)-tert-butyl 2-(5-bromo-1H-imidazol-2-yl)-4-methylpyrrolidin-1-carboxylate (206 mg, 0.54 mmol), tetrakis(triphenylphosphine) palladium(0) (49 mg, 0.042 mmol) and dichloro[1,1′-bis(diphenylphosphino)ferrocene]palladium(II) (31 mg, 0.042 mmol) in DMSO (3 mL) and dioxanes (3 mL) was added a solution of potassium carbonate (2M in water, 0.69 mL, 1.39 mmol). The resulting mixture was degassed and then heated to 95° C. for 2 h. After cooling to room temperature, the reaction was diluted with ethyl acetate. The organics were washed with saturated sodium bicarbonate and brine, dried over Na2SO4 and concentrated. The crude residue was purified by flash chromatography (1 to 20% MeOH/EtOAc) to yield tert-butyl (2S,4S)-2-[5-(2-{(2S,5S)-1-[N-(methoxycarbonyl)-L-valyl]-5-methylpyrrolidin-2-yl}-1,11-dihydroisochromeno[4′,3′:6,7]naphtho[1,2-d]imidazol-9-yl)-1H-imidazol-2-yl]-4-methylpyrrolidine-1-carboxylate (202 mg, 63%).
