Procedure

To a solution of 6,6′-{(2R,5R)-1-[3,5-difluoro-4-(piperidin-1-yl)phenyl]pyrrolidine-2,5-diyl}bis{5-fluoro-2-[(2S)-pyrrolidin-2-yl]-1H-benzimidazole} (64 mg, 0.095 mmol) in DMF (2378 μL) was added (S)-2-(methoxycarbonylamino)-3-methylbutanoic acid (35.0 mg, 0.200 mmol), EDC (45.6 mg, 0.238 mmol), HOBT (36.4 mg, 0.238 mmol) and N-methylmorpholine (105 μL, 0.951 mmol), and the resultant solution was stirred at ambient temperature overnight. The reaction solution was diluted with EtOAc, washed with H2O and brine, dried (MgSO4), filtered and concentrated. The crude material was dissolved in 1:1 CH3CN:0.1% TFA/H2O and purified by HPLC (C18, 0-100% CH3CN/0.1% TFA/H2O). The product containing fractions were combined, made basic with saturated sodium bicarbonate solution, and extracted with EtOAc. The organic layer was dried (MgSO4), filtered and concentrated to give the title compound (43.3 mg, 0.044 mmol, 46.1% yield). The title compound can also be prepared according to General Procedure 12C described above. 1H NMR (400 MHz, CDCl3) δ ppm 10.25-10.70 (m, 2H) 6.83-7.53 (m, 4H) 5.70-5.91 (m, 2H) 5.20-5.52 (m, 4H) 4.21-4.42 (m, 2H) 3.70 (s, 6H) 3.53-3.94 (m, 6H) 1.75-3.17 (m, 16H) 0.63-1.74 (m, 18H); MS (ESI) m/z 987 (M+H)+.
