Procedure
To a mixture of N-methyl-2-(4-methylisoxazol-3-yl)-6-(N-methylmethylsulfonamido)-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzofuran-3-carboxamide (60 mg, 0.12 mmol), 2-chloro-11-fluoro-5,6-dihydroindolo[1,2-h][1,7]naphthyridine (50 mg, 0.18 mmol) and K3PO4.3H2O (98 mg, 0.37 mmol) in dioxane/H2O (1.5 mL/0.5 mL) was added Pd2(dba)3 (8 mg, 0.008 mmol) and X-Phos (8 mg, 0.016 mmol) under N2. The mixture was stirred at 85° C. for 3 h. It was concentrated, diluted with water, extracted with EtOAc, and dried over Na2SO4. The residue was purified by prep-TLC (DCM:MeOH=60:1) to get the product (35 mg, yield: 48%). 1H-NMR (CDCl3, 400 MHz) δ 9.12 (d, J=3.6 Hz, 1H), 8.68 (s, 1H), 8.40 (s, 1H), 7.76 (s, 1H), 7.68 (d, J=7.6 Hz, 1H), 7.48 (d, J=7.6 Hz, 1H), 7.28˜7.26 (m, 1H), 7.21˜7.12 (m, 2H), 6.85˜6.75 (m, 1H), 4.36 (t, J=6.4 Hz, 2H), 3.46 (s, 3H), 3.33 (t, J=6.4 Hz, 2H), 3.03 (d, J=4.8 Hz, 3H), 2.60 (s, 3H), 2.40 (s, 3H). MS (M+H)+: 600.
