Procedure

To a flask was added a 2-amino-6-bromo-4-methyl-8-(pyrrolidin-1-yl)pyrido[2,3-d]pyrimidin-7(8H)-one (21.0 mg, 0.06 mmol), tert-butyl 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole-1-carboxylate (20.9 mg, 0.07 mmol) potassium carbonate (25.6 mg, 0.19 mmol) in DMAC (1.20 ml):H2O (0.1 ml). The reaction mixture was degassed by alternating between N2 and vacuum. To the reaction mixture was added PdCl2(PPh3)2 (4.3 mg). After heating in microwave for 60 min at 100° C., the reaction mixture was concentrated under reduced pressure and the resulting residue was purified by reversed phase column eluted with acetonitrile: 0.1% acetic acid in water to give the titled compound weighted 2.5 mg
