Procedure
To a mixture of N-methyl-2-(4-methyl-2-oxopyridin-1 (2H)-yl)-6-(N-methylmethylsulfonamido)-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzofuran-3-carboxamide (100 mg, 0.19 mmol), 2-chloro-11-fluoro-5,6-dihydroindolo[1,2-h][1,7]naphthyridine (63 mg, 0.23 mmol) and K2CO3 (54 mg, 0.39 mmol) in 1,4-dioxane/H2O (3 mL/0.1 mL) were added X-Phos (10 mg) and Pd2(dba)3 (10 mg) under N2. The reaction mixture was stirred at 80° C. for 5 hours and concentrated in vacuo to remove 1,4-dioxane. The reaction mixture was extracted with EtOAc, washed with brine, dried over Na2SO4, filtered and concentrated in vacuo. The residue was purified by prep-HPLC to give the product (30 mg, yield: 24%). 1H-NMR (CDCl3, 400 MHz) δ 8.17 (s, 1H), 7.83˜7.85 (m, 1H), 7.66˜7.68 (m, 2H), 7.44 (d, J=8.0 Hz, 1H), 7.26˜7.18 (m, 2H), 7.14˜7.18 (m, 2H), 6.77˜6.81 (m, 1H), 6.53 (s, 1H), 6.29 (d, J=8.0 Hz, 1H), 4.34 (t, J=6.4 Hz, 2H), 3.40 (s, 3H), 3.31 (t, J=6.4 Hz, 2H), 2.90 (d, J=4.8 Hz, 3H), 2.61 (s, 3H), 2.32 (s, 3H). MS (M+H)+: 626.
