実験手順

A solution of (S)-tert-butyl 2-(6-(7-(2-((S)-1-((S)-2-(methoxycarbonylamino)-3-methylbutanoyl)pyrrolidin-2-yl)-1H-imidazol-5-yl)-9,10-dihydrophenanthren-2-yl)-1H-benzo[d]imidazol-2-yl)pyrrolidine-1-carboxylate (30 mg, 0.04 mol), methanol (0.5 mL), and 4M HCl in dioxane (1 mL, 4 mmol) was stirred at room temperature. The reaction was thoroughly concentrated after twenty minutes. The resulting residue was dissolved in a 4:1 dichloromethane:dimethylformamide solution (1.0 mL). One half of this solution was removed and used in the subsequent reaction. To this solution (˜0.5 mL) was added (R)-2-(methoxycarbonylamino)-2-phenylacetic acid (4.2 mg, 0.02 mmol) and COMU (8.5 mg, 0.02 mmol) and the reaction was cooled to 0° C. Diisopropylethylamine (0.011 mL, 0.06 mmol) was added and the reaction was stirred at 0° C. for twenty minutes. The reaction was quenched by the addition of formic acid (0.05 mL) and thoroughly concentrated. The resulting residue was purified by preparative reverse phase HPLC (Gemini, 10 to 60% ACN/H2O+0.1% HCO2H), followed by a second preparative reverse phase HPLC (Gemini, 10 to 60% ACN/H2O+0.1% TFA) to yield methyl (S)-1-((S)-2-(5-(7-(2-((S)-1-((R)-2-methoxycarbonylamino-2-phenylacetyl)pyrrolidin-2-yl)-1H-benzo[d]imidazol-6-yl)-9,10-dihydrophenanthren-2-yl)-1H-imidazol-2-yl)pyrrolidin-1-yl)-3-methyl-1-oxobutan-2-ylcarbamate (6 mg, 36%). LCMS-ESI+: calculated for C49H52N8O6: 848.99; observed [M+1]+: 850.2.
