실험 절차

To a degassed solution of 5-(6-chloro-5-formylpyridin-2-yl)-2-(4-fluorophenyl)-N-methyl-6-(N-methylmethylsulfonamido)benzofuran-3-carboxamide (150 mg, 0.29 mmol) and 4-fluoro-2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-indole (94 mg, 0.35 mmol) in 1,4-dioxane (3 mL) and water (200 μL) was added CS2CO3 (189 mg, 0.58 mmol) and 1,1′-bis(di-tert-butylphosphino)ferrocene palladium chloride (30 mg, 0.05 mmol) under N2 protection. The resulting mixture was heated to 90° C. and stirred for 3 hours. The reaction was cooled, filtered through a pad of celite and washed with ethyl acetate. The combined filtrate was evaporated in vacuo. Preparative TLC (eluted with (30% ethyl acetate/DCM) to provide 5-(10-fluoro-5-hydroxy-5H-pyrido[2′,3′:3,4]pyrrolo[1,2-a]indol-2-yl)-2-(4-fluorophenyl)-N-methyl-6-(N-methylmethylsulfonamido)benzofuran-3-carboxamide (40 mg, yield: 22%) MS (M+H)+: 615.
