Versuchsvorschrift

A solution of tert-butyl(2S,4S)-2-[5-(2-{(2S,5S)-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 (80 mg, 0.11 mmol) in 1.25 N HCl in EtOH (2 mL) was heated to 50° C. for 3 h. The reaction was concentrated and the crude material dissolved in DMF (1.5 mL). To this solution was added a solution of (R)-2-(methoxycarbonylamino)-2-phenylacetic acid (29 mg, 0.14 mmol) and COMU (52 mg, 0.12 mmol). To the resulting solution was added diisopropylethylamine (0.057 mL, 0.33 mmol). After stirring for 2 h at room temperature, the reaction was quenched with 1N HCl (0.200 mL) and purified by HPLC. After lyophilization, the TFA salt was dissolved in EtOAc and washed with saturated NaHCO3. The organic phase was dried over Na2SO4 and concentrated. The free base was then dissolved in MeCN/H2O and lyophilized to afford methyl{(2S)-1-[(2S,5S)-2-(9-{2-[(2S,4S)-1-{(2R)-2-[(methoxycarbonyl)amino]-2-phenylacetyl}-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: (42 mg, 45%). LCMS-ESI+: calculated for C48H52N8O7: 852.4; observed [M+1]+: 854.2.
