Reaction Steps

To a degassed mixture of 6-bromo-3-(2-fluorophenyl)pyrido[2,3-d]pyrimidin-4(3H)-one (100 mg, 0.313 mmol), and 2-(4-fluorophenyl)-N-methyl-6-(N-methylmethylsulfonamido)-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzofuran-3-carboxamide (100 mg, 0.199 mmol) in N, N-dimethyl-formamide (5 mL) were added Pd(dppf)Cl2 (15 mg) and K3PO4 (135 mg, 0.637 mmol) under N2. The mixture was heated to 80° C. overnight. The reaction mixture was cooled to RT and filtered. The filtrate was concentrated, and the residue was purified by prep-HPLC to give 2-(4-fluorophenyl)-5-(3-(2-fluorophenyl)-4-oxo-3,4-dihydropyrido[2,3-d]pyrimidin-6-yl)-N-methyl-6-(N-methylmethylsulfonamido)benzofuran-3-carboxamide (11.78 mg, yield: 10%). 1H-NMR (CDCl3, 400 MHz) δ 9.12 (d, J=2.0 Hz, 1H), 8.77 (d, J=2.0 Hz, 1H), 8.33 (s, 1H), 7.94 (t, J=6.8 Hz, 3H), 7.68 (s, 1H), 7.54˜7.59 (m, 1H), 7.47 (t, J=6.8 Hz, 1H), 7.33˜7.39 (m, 2H), 7.21 (t, J=8.4 Hz, 2H), 6.04 (d, J=4.4 Hz, 1H), 3.27 (s, 3H), 3.01 (d, J=4.8 Hz, 3H), 2.83 (s, 3H). MS (M+H)+: 616.
