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 3h and then concentrated under reduced pressure. The crude residue was treated with (2S,3R)-3-methoxy-2-(methoxycarbonylamino)butanoic acid (35 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 hr, the mixture was quenched with 1N HCl (0.100 mL) and then purified by HPLC to afford methyl {(2S,3R)-1-[(2S,4S)-2-(5-{2-[(2S,4S)-1-[N-(methoxycarbonyl)-O-methyl-L-allothreonyl]-4-(methoxymethyl)pyrrolidin-2-yl]-1,11-dihydroisochromeno[4′,3′:6,7]naphtho[1,2-d]imidazol-9-yl}-1H-imidazol-2-yl)-4-methylpyrrolidin-1-yl]-3-methyl-1-oxopentan-2-yl}carbamate (92 mg, 81%).
