Reaction Steps

To 5-chloro-7-{[3-(diethylamino)propyl]amino}-1-(2,6-difluorophenyl)-3,4-dihydropyrimido[4,5-d]pyrimidin-2(1H)-one (207 mg, 0.488 mmol) in 1,4-dioxane (7.5 mL) and water (2.5 mL) was added 4-methyl-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzoic acid (0.192 g, 0.733 mmol), tetrakis(triphenylphosphine)-palladium(0) (28.3 mg, 0.024 mmol), and potassium carbonate (270 mg, 1.95 mmol). The mixture was heated with microwave for 15 min at 150° C., and then allowed to cool to room temperature. The mixture was concentrated and separated by HPLC to afford the title compound (66 mg, 26%). LC-MS m/z 525 (M+H)+.
