Procedure

A mixture of [(4S,6S)-6-(3,5-difluorophenyl)-4-hydroxy-3,3-dimethyl-2-oxopiperidin-1-yl]acetic acid (130 mg, 0.415 mmol, described in Intermediate 21), (R)-5-amino-1,3-dihydro spiro[indene-2,3′-pyrrolo[2,3-b]pyridin]-2′(1′H)-one (140 mg, 0.557 mmol, described in Intermediate 9), HOBT (82 mg, 0.535 mmol), and EDC (95 mg, 0.498 mmol) in DMF (2 mL) was stirred at ambient temperature for 6 h. The reaction mixture was partitioned between H2O (50 mL), saturated aqueous NaHCO3 (30 mL) and EtOAc (100 mL). The organic layer was dried over Na2SO4, filtered, and concentrated in vacuo. The crude product was purified by silica gel chromatography, eluting with a gradient of CH2Cl2:CH3OH—100:0 to 90:10, to give the title compound. MS: m/z=547 (M+1). HRMS: m/z=547.2169; calculated m/z=547.2151 for C30H29F2N4O4.
