실험 절차

A stirred mixture of (±)-2-chloro-6,8-dihydrospiro[cyclopenta[g]quinoline-7,3′-pyrrolo[2,3-b]pyridin]-2′(1′H)-one (204 mg, 0.634 mmol, described in Intermediate 20), 3-methoxycarbonylphenylboronic acid (229 mg, 1.27 mmol), PdCl2(PPh3)2 (44 mg, 0.063 mmol), and potassium carbonate (290 mg, 2.10 mmol), in 1,2-dimethoxyethane (3 mL) and H2O (1 mL) was heated at 80° C. for 18 h. The cooled mixture was partitioned between H2O (40 mL) and EtOAc (40 mL). The organic layer was removed and the aqueous phase was extracted further with EtOAc (40 mL). The combined organic extracts were washed with brine, dried over Na2SO4, filtered, and concentrated under reduced pressure. The residue was purified 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 product-containing fractions were combined and concentrated to give the title compound. MS: m/z=422 (M+1). HRMS: m/z=422.1504; calculated m/z=422.1499 for C26H20N3O3.
