Reaction Steps

(S)-tert-butyl 2-(5-(6-(2-((S)-1-((S)-2-(methoxycarbonylamino)-3-methylbutanoyl)pyrrolidin-2-yl)-1H-naphtho[1,2-d]imidazol-7-yl)naphthalen-2-yl)-1H-imidazol-2-yl)pyrrolidine-1-carboxylate (88 mg, 0.116 mmol) was dissolved in DCM (5 mL) and HCl (4M in dioxane, 1 mL) was added. After stirring for 1 h, the reaction mixture was concentrated and the residue was treated with (R)-2-(methoxycarbonylamino)-2-phenylacetic acid (24 mg, 0.116 mmol), COMU (50 mg, 0.116 mmol) and DMF (3 mL). DIPEA (0.101 mL, 0.58 mmol) was added and the mixture was stirred for 13 min before being quenched with H2O and purified by HPLC to afford the title compound (61 mg, 62%). MS: (ESI) m/z 847 [M+H]+.
