Procedure

A mixture of [(6R)-6-(3,5-difluorophenyl)-3,3-diethyl-2-oxopiperazin-1-yl]acetic acid hydrochloride (43 mg, 0.119 mmol, described in Intermediate 29), (R)-5-amino-1,3-dihydrospiro[indene-2,3′-pyrrolo[2,3-b]pyridin]-2′(1′H)-one (30 mg, 0.119 mmol, described in Intermediate 9), HOBT (27 mg, 0.179 mmol), and EDC (34 mg, 0.179 mmol) in DMF (0.5 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. The pure, product-containing fractions were combined, basified with saturated aqueous NaHCO3, and extracted with EtOAc. The organic extracts were dried over Na2SO4, filtered, and concentrated in vacuo to give the title compound. MS: m/z=560 (M+1). HRMS: m/z=560.2469; calculated m/z=560.2468 for C31H32F2N5O3.
