Procedure

To the compound 4-chloro-8-(2,6-difluorophenyl)-2-(4-methyl-1,4′-bipiperidin-1′-yl)pyrido[2,3-d]pyrimidin-7(8H)-one (47.5 mg, 0.1 mmol) in dioxane (3 mL) and water (1 mL) were added 6-methyl-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzoic acid (38.4 mg, 0.15 mol), potassium carbonate (83 mg, 0.6 mmol) and tetrakis(triphenylphosphine)palladium(0) (4.6 mL, 0.005 mmol). The mixture was heated with microwave at 150° C. for 15 min. The mixture was concentrated, & then added was DMSO (0.75 mL) and water (0.25 mL). Separation by HPLC afforded the title compound (39 mg, 68%). LC-MS m/z 574 (M+H)+.
