Versuchsvorschrift

Tert-butyl (2S,4S)-2-[5-(2-{(2S,4S)-1-[N-(methoxycarbonyl)-L-valyl]-4-(methoxymethyl)pyrrolidin-2-yl}-1,11-dihydroisochromeno[4′,3′:6,7]naphtho[1,2-d]imidazol-9-yl)-1H-imidazol-2-yl]-4-methylpyrrolidine-1-carboxylate (174 mg, 0.24 mmol) was dissolved in DCM (4 mL), MeOH (1 mL) and HCl (4 M in dioxane, 1 mL) was added. The reaction mixture was stirred for h and then concentrated under reduced pressure. The crude residue was treated with ((2S,3R)-3-methoxy-2-(methoxycarbonylamino)butanoic acid (92 mg, 0.48 mmol), HATU (182 mg, 0.48 mmol) and DMF (5 mL), then DIPEA (0.31 mL, 2.4 mmol) was added dropwise. After 35 min, the mixture was diluted with 10% MeOH/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 HPLC to afford methyl {(2S,3R)-3-methoxy-1-[(2S,4S)-2-[9-(2-{(2S,4S)-1-[N-(methoxycarbonyl)-O-methyl-L-threonyl]-4-methylpyrrolidin-2-yl}-1H-imidazol-5-yl)-1,11-dihydroisochromeno[4′,3′:6,7]naphtho[1,2-d]imidazol-2-yl]-4-(methoxymethyl)pyrrolidin-1-yl]-1-oxobutan-2-yl}carbamate (72 mg, 34%).
