Procedure

To the compound 4-chloro-2-{[3-(diethylamino)propyl]amino}-8-(2,6-difluorophenyl)pyrido[2,3-d]pyrimidin-7(8H)-one (176 mg, 0.418 mmol) in dioxane (4.5 mL) and water (1.5 mL) was added 2-methyl-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzoic acid (173 mg, 0.626 mol), potassium carbonate (289 mg, 2.09 mmol) and tetrakis(triphenylphosphine)palladium(0) (24.2 mg, 0.0259 mmol). The mixture was heated with microwave at 150° C. for 15 min. The mixture was filtered. Separation by HPLC with TFA afforded the title compound (238 mg, 99%). LC-MS m/z 522 (M+H)+.
