Procedure

To the solution of 5-chloro-1-(2,6-difluorophenyl)-7-{[2-(dimethylamino)ethyl]amino}-3,4-dihydropyrimido[4,5-d]pyrimidin-2(1H)-one (191 mg, 0.50 mmol) in dioxane (15 mL) and water (5 mL) were added 4-methyl-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzoic acid (197 mg, 0.75 mmol), K2CO3 (415 mg, 3.0 mmol) and tetrakis(triphenyl-phosphine)palladium(0) (23 mg, 0.025 mmol). The reaction mixture was heated to 150° C. for 15 minutes with microwave. The reaction mixture was concentrated to dry then was added DMSO (2 mL), water (0.5 mL) and HOAc (1 drop). The solution was filtered and applied to the reverse phase HPLC to afford the titled compound 0.24 g (quantitative). LC-MS m/z 483 (M+H)+; 1H-NMR (MeOD) 2.36 (s, 3H), 2.76 (s, 6H), 3.16 (s, 2H), 3.56 (s, 2H), 4.13 (s, 2H), 7.21 (m, 1H), 7.53 (m, 2H), 7.95 (s, 1H), 8.09 (d, J=7.6 Hz, 1H).
