Procedure

To a solution of 2-(4-cyanophenyl)-N-methyl-6-(N-methylmethylsulfonamido)-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzofuran-3-carboxamide (115 mg, 0.22 mmol), 2-chloro-11-fluoro-6H-pyrido[2′,3′:5,6][1,3]oxazino[3,4-a]indole (75 mg, 0.27 mmol) K2CO3 (60 mg, 0.44 mmol), Pd2(dba)3 (30 mg) and X-Phos (30 mg) in dioxane/H2O (3 mL/0.6 mL) was stirred at 100° C. for 3 h. The reaction was filtered to remove the solid and then the mixture was diluted with water and extracted with EA. The organic layer was washed with brine, dried over Na2SO4 and concentrated. The residue was purified by prep-HPLC to get the product of 2-(4-cyanophenyl)-5-(11-fluoro-6H-pyrido[2′,3′:5,6][1,3]oxazino[3,4-a]indol-2-yl)-N-methyl-6-(N-methylmethylsulfonamido)benzofuran-3-carboxamide (30 mg, yield: 21%). 1H-NMR (CDCl3, 400 MHz) δ 8.16 (d, J=8.4 Hz, 2H), 7.96 (s, 1H), 7.78 (d, J=8.4 Hz, 2H), 7.70 (s, 1H), 7.23˜7.19 (m, 3H), 7.13 (d, J=8.4 Hz, 2H), 6.87 (m, 1H), 6.14 (d, J=4.4 Hz, 1H), 6.00 (s, 2H), 3.35 (s, 3H), 3.05 (d, J=5.2 Hz, 3H), 2.77 (s, 3H).
