Procedure

tert-butyl(2S,4S)-2-[5-(2-{(2S,5 S)-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 (60 mg, 0.079 mmol) in 1.25 N HCl in EtOH (2 mL) was heated to 50° C. for 3 h and then concentrated under reduced pressure. The crude residue was treated with (S)-2-(methoxycarbonylamino)-3-methylbutanoic acid (21 mg, 0.12 mmol), HATU (36 mg, 0.095 mmol) and DMF (1.5 mL), then N-methylmorpholine (0.027 mL, 0.24 mmol) was added dropwise. After 3 h, the mixture was quenched with 1N HCl (0.100 mL) and then purified by HPLC to afford methyl{(2S)-1-[(2S,5S)-2-(9-{2-[(2S,4S)-1-{(2S)-2-[(methoxycarbonyl)amino]-3-methylbutanoyl}-4-methylpyrrolidin-2-yl]-1H-imidazol-5-yl}-1,11-dihydroisochromeno[4′,3′:6,7]naphtho[1,2-d]imidazol-2-yl)-5-methylpyrrolidin-1-yl]-3-methyl-1-oxobutan-2-yl}carbamate (33 mg, 51%).
