실험 절차

(2S,4S)-Tert-butyl 4-(methoxymethyl)-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)pyrrolidine-1-carboxylate (856 mg, 1.4 mmol), methyl (2S,3S)-1-((2S,4S)-2-(5-bromo-1H-imidazol-2-yl)-4-methylpyrrolidin-1-yl)-3-methyl-1-oxopentan-2-ylcarbamate (932 mg, 2.1 mmol), Pd(PPh3)4 (162 mg, 0.14 mmol), PdCl2(dppf)2 (102 mg, 0.14 mmol), and K2CO3 (2M in H2O, 2.31 mL, 4.62 mmol) were combined in DMSO (8 mL) and dioxanes (8 mL). The mixture was degassed with bubbling Argon for 10 min then heated to 95° C. for 1 h. After cooling, the reaction mixture was diluted with EtOAc, and washed successively with saturated aqueous NaHCO3 and brine. The organics were dried over Na2SO4, filtered and concentrated under reduced pressure. The crude residue was purified by silica column chromatography (1% to 20% MeOH/EtOAc) to afford tert-butyl (2S,4S)-2-[9-(2-{(2S,4S)-1-[N-(methoxycarbonyl)-L-alloisoleucyl]-4-methylpyrrolidin-2-yl}-1H-imidazol-5-yl)-1,11-dihydroisochromeno[4′,3′:6,7]naphtho[1,2-d]imidazol-2-yl]-4-(methoxymethyl)pyrrolidine-1-carboxylate (701 mg, 62%).
