Procedure

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 (105 mg, 0.13 mmol) in 1.25 N HCl in EtOH (3 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 (32 mg, 0.18 mmol), HATU (59 mg, 0.16 mmol) and DMF (1.3 mL), then N-methylmorpholine (0.043 mL, 0.39 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,4S)-2-(9-{2-[(2S,4S)-1-{(2S,3R)-2-[(methoxycarbonyl)amino]-3-methylpentanoyl}-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]-3-methyl-1-oxobutan-2-yl}carbamate (80 mg, 71%).
