Reaction Steps

To the compound 4-chloro-2-{[3-(diethylamino)propyl]amino}-8-(2,6-difluorophenyl)pyrido[2,3-d]pyrimidin-7(8H)-one (168.75 mg, 0.40 mmol) in dioxane (12 mL) and water (4 mL) were added 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzoic acid (148.85 mg, 0.60 mol), potassium carbonate (208 mg, 1.20 mmol) and tetrakis(triphenylphosphine)palladium(0) (23 mg, 0.02 mmol). The mixture was heated with microwave at 150° C. for 15 min. The mixture was concentrated. It was mixed with DMSO (0.75 mL) and water (0.25 mL). Separation by HPLC afforded the title compound (147 mg, 72%). LC-MS m/z 508 (M+H)+.
