Procedure

A solution of (2S,4S)-tert-butyl-2-(9-(2-((S)-1-((S)-2-(methoxycarbonylamino)-3-methylbutanoyl)pyrrolidin-2-yl)-1H-benzo[d]imidazol-6-yl)-1,11-dihydroisochromeno[4′,3′:6,7]naphtho[1,2-d]imidazol-2-yl)-4-(methoxymethyl)pyrrolidine-1-carboxylate (156 mg, 0.18 mmol), ethanol (3 mL) and concentrated HCl (1 mL) was heated to 60° C. for 1 hour. The reaction was concentrated and the crude material dissolved in DCM (6 mL). This solution was concentrated and to (68 mg, 0.09 mmol) of this material was added a solution of (R)-2-(methoxycarbonylamino)-2-phenylacetic acid (21 mg, 0.12 mmol) and COMU (41 mg, 01 mmol) in DMF (1 mL). To the resulting solution was added diisopropylethylamine (50 μL, 0.28 mmol). After stirring for 2 hours at room temperature, the reaction was diluted with ethyl acetate, washed with water and brine, dried (Na2SO4), concentrated and purified by preparative reverse phase HPLC (Gemini, 15 to 44% ACN/H2O+0.1% TFA). The product fractions were lyophilized to give methyl {(2S)-2-[(2S,4S)-2-{9-[2-((2S)-1-{(2S)-2-[(methoxycarbonyl)amino]-3-methylbutanoyl}pyrrolidin-2-yl)-1H-benzo[d]imidazol-6-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 (32 mg, 40%). MS (ESI) m/z 886 [M+H]f.
