反応手順
To a solution of (2S)-2-[methoxycarbonyl(methyl)amino]-3-methyl-butanoic acid (12.8 mg, 0.06765 mmol) and methyl methyl((S)-3-methyl-1-((2S,4S)-4-methyl-2-(6-(4′-(2-((2S,4S)-4-methylpyrrolidin-2-yl)-1H-imidazol-5-yl)[1,1′-biphenyl]-4-yl)-1H-benzo[d]imidazol-2-yl)pyrrolidin-1-yl)-1-oxobutan-2-yl)carbamate hydrochloride (48.1 mg, 0.0677 mmol) in DMF (2 mL) cooled in an ice bath is sequentially added HATU (28.3 mg, 0.0744 mmol) and DIPEA (0.035 mL, 0.203 mmol) under nitrogen atmosphere. The reaction mixture is stirred at room temperature for 19 hours and diluted with saturated aqueous NaHCO3 (2 mL). The mixture is extracted with EtOAc (5×3 mL), and the combined organic layers are washed with H2O (3×3 mL), dried over Na2SO4, filtered, and concentrated to dryness. The residue is purified by reverse phase preparative HPLC to give methyl N-[(1S)-1-[(2S,4S)-2-[4-[4-[4-[2-[(2S,4S)-1-[(2S)-2-[methoxycarbonyl(methyl)amino]-3-methyl-butanoyl]-4-methyl-pyrrolidin-2-yl]-1H-benzimidazol-5-yl]phenyl]phenyl]-1H-imidazol-2-yl]-4-methyl-pyrrolidine-1-carbonyl]-2-methyl-propyl]-N-methyl-carbamate (24.4 mg, 41%).
