Reaction Steps

To a solution of 7-chloro-2-(3-fluorophenyl)-2,3-dihydropyrido[2,3-d]pyrimidin-4(1H)-one (66 mg, 0.237 mmol), 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) and K3PO4.3H2O (106 mg, 0.398 mmol) in 1 mL of dioxane and 0.1 mL of water were added X-phos (10 mg) and Pd2(dba)3 (10 mg) under nitrogen. The mixture was heated at 100° C. for 6 h, concentrated in vacuo and the residue was suspended in water. The mixture was extracted with EtOAc and the organic phase was washed with brine, then dried over sodium sulfate. 2-(4-fluorophenyl)-5-(2-(3-fluorophenyl)-4-oxo-1,2,3,4-tetrahydropyrido[2,3-d]pyrimidin-7-yl)-N-methyl-6-(N-methylmethylsulfonamido)benzofuran-3-carboxamide (60 mg, yield: 49%) was obtained by the prep-TLC (PE:EtOAc=1:2). 1H-NMR (CD3OD, 400 MHz) δ 8.06 (d, J=7.6 Hz, 1H), 7.91˜7.95 (m, 2H), 7.81 (s, 1H), 7.77 (s, 1H), 7.37˜7.40 (m, 1H), 7.32 (d, J=8.0 Hz, 1H), 7.21˜7.27 (m, 3H), 7.02˜7.08 (m, 2H), 5.96 (s, 1H), 3.27 (d, J=6.0 Hz, 3H), 2.90 (s, 3H), 2.80 (s, 3H). MS (M+H)+: 618.
