실험 절차

A mixture of 2-bromo-11-fluoro-5,6-dihydroindolo[2,1-f][1,6]naphthyridine (50 mg, 0.16 mmol), 2-(4-fluorophenyl)-N-methyl-6-(N-methylmethylsulfonamido)-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzofuran-3-carboxamide (87 mg, 0.17 mmol), potassium carbonate (43 mg, 0.32 mmol) and Pd(dtbpf)Cl2 (10 mg) in 1,4-dioxane/water (1/0.1 mL) was stirred at 100° C. for 6 hours under nitrogen atmosphere. The mixture was filtered through Celite pad and concentrated, and then the residue was diluted with water and EA. After extraction with EA, the combined organic phase was washed with brine, dried over sodium sulfate and concentrated to afford the desired product (40 mg, yield: 41.7%) through the prep-HPLC. 1H-NMR (CDCl3, 400 MHz) δ 8.50 (s, 1H), 8.19 (s, 1H), 7.93˜7.96 (m, 2H), 7.90 (s, 1H), 7.65 (s, 1H), 7.19˜7.24 (m, 2H), 7.15˜7.17 (m, 2H), 7.02 (s, 1H), 6.77˜6.82 (m, 1H), 5.88 (br s, 1H), 4.41˜4.44 (m, 2H), 3.45˜3.49 (m, 2H), 3.18 (s, 3H), 2.99 (d, J=4.80 Hz, 3H), 2.84 (s, 3H). MS (M+H)+: 613.
