Reaction Steps

(2S,4S)-tert-Butyl 2-(2′-((2S,4S)-1-((S)-2-(methoxycarbonylamino)-3-methylbutanoyl)-4-methylpyrrolidin-2-yl)-1H,1′H-7,7′-binaphtho[1,2-d]imidazol-2-yl)-4-(methoxymethyl)pyrrolidine-1-carboxylate (120 mg, 0.152 mmol) was dissolved in DCM (5 mL) and treated with HCl (4.0 mL in dioxane, 1 mL). After stirring for 1 h, the reaction mixture was concentrated under reduced pressure. The crude residue was treated with (2S,3R)-3-methoxy-2-(methoxycarbonylamino)butanoic acid (35 mg, 0.18 mmol), HATU (69 mg, 0.18 mmol), DMF (1 mL) and DIPEA (0.26 mL, 1.5 mmol). After 20 min, the reaction was quenched with water. The product was purified by reverse-phase HPLC to afford methyl (S)-1-((2S,4S)-2-(2′-((2S,4S)-1-((2S,3R)-2-methoxycarbonylamino-3-methoxybutanoyl)-4-(methoxymethyl)pyrrolidin-2-yl)-1H,1′H-7,7′-binaphtho[1,2-d]imidazol-2-yl)-4-methylpyrrolidin-1-yl)-3-methyl-1-oxobutan-2-ylcarbamate (120 mg). MS (ESI) m/z 862 [M+H]+.
