Procedure

To a solution of methyl (S)-3-methyl-1-oxo-1-((S)-2-(5-(4′-(2-((S)-pyrrolidin-2-yl)-1H-imidazol-5-yl)biphenyl-4-yl)-1H-imidazol-2-yl)pyrrolidin-1-yl)butan-2-ylcarbamate (cj-13) (0.060 g, 0.103 mmol) in DMF (2 mL) was added iPr2NEt (0.18 mL, 1.02 mmol), (S)-3-methyl-2-(pyridin-3-ylamino)butanoic acid (Cap-88) (0.040 g, 0.206 mmol) and HATU (0.078 g, 0.205 mmol). The reaction mixture was stirred for 1.5 h at room temperature and then it was directly purified by prep HPLC (Luna 5u C18/MeCN—H2O—NH4OAc). The resulting solid was repurified by flash chromatography (SiO2/0-10% MeOH—CH2Cl2) and the obtained product was lyophilized from CH3CN—H2O to give the title compound (0.044 g, 56%) as a solid.
