A mixture of (2-oxo-3-pyridin-2-yl-2,3-dihydro-1H-benzimidazol-1-yl)acetic acid (16 mg, 0.060 mmol, described in Intermediate 7), (±)-2-amino-5,7-dihydrospiro[cyclopenta[b]pyridine-6,3′-pyrrolo[2,3-b]pyridin]-2′(1W)-one (15 mg, 0.060 mmol, described in Intermediate 5), PyClu (26 mg, 0.072 mmol), and DIEA (0.053 mL, 0.30 mmol) in THF (1 mL) was stirred at ambient temperature for 18 h. The reaction mixture was purified directly by HPLC using a reversed phase C18 column and eluting with a gradient of H2O:CH3CN:CF3CO2H—90:10:0.1 to 5:95:0.1. Lyophilization provided the title compound. MS: m/z=504 (M+1). HRMS: m/z=504.1796; calculated m/z=504.1779 for C28H22N7O3.
