実験手順

Methyl [(2S)-3-methyl-1-{(2S,4S)-4-methyl-2-[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 (298 mg, 0.47 mmol), (S)-tert-butyl 2-(5-bromo-1H-imidazol-2-yl)pyrrolidine-1-carboxylate (443 mg, 1.4 mmol), Pd(PPh3)4 (54 mg, 0.05 mmol), PdCl2(dppf)2 (36 mg, 0.05 mmol), and K2CO3 (2M in H2O, 0.78 mL, 1.55 mmol) were combined in DME (5 mL). The mixture was degassed with bubbling N2 for 10 min then heated to 85° C. for 16 h. After cooling, the reaction mixture was diluted with EtOAc, and washed successively with saturated aqueous NaHCO3 and brine. The organics were dried over MgSO4, filtered and concentrated under reduced pressure. The crude residue was purified by silica column chromatography (0% to 30% MeOH/EtOAc) to afford tert-butyl (2S)-2-[5-(2-{(2S,4S)-1-[N-(methoxycarbonyl)-L-valyl]-4-methylpyrrolidin-2-yl}-1,11-dihydroisochromeno[4′,3′:6,7]naphtho[1,2-d]imidazol-9-yl)-1H-imidazol-2-yl]pyrrolidine-1-carboxylate (84 mg, 24%).
