Procedure

To a solution of 8-chloro-N-(2-methyl-4-(1-methyl-1H-pyrazol-4-yl)phenyl)pyrido[3,4-d]pyrimidin-2-amine (Preparation 113, 12 mg, 0.034 mmol) in 1,4-dioxane (2 mL) and water (1 mL) was added 1-methylpyrazole-4-boronic acid pinacol ester (14 mg, 0.068 mmol), cesium carbonate (17 mg, 0.051 mmol) and Pd(PPh3)4 (2 mg, 1.71 umol). The reaction mixture was heated to 100° C. under microwave irradiation for 30 minutes. The reaction mixture was diluted with EtOAc (20 mL) and water (20 mL). The organic layer was washed with water (20 mL) and brine (20 mL), dried (MgSO4) and concentrated in vacuo. The residue was purified by silica gel column chromatography eluting with 0-15% MeOH in EtOAc to give the title compound (7 mg, 52%).
