Reaction Steps

A solution of 8-chloro-N-(2-methoxy-4-(1-methyl-1H-pyrazol-4-yl)phenyl)pyrido[3,4-d]pyrimidin-2-amine (Example 94, 35 mg, 0.095 mmol), 1-ethyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (32 mg, 0.144 mmol) and Pd(dppf)Cl2.DCM (8 mg, 9.79 μmol) was dissolved in THF (0.6 mL) and 2M sodium carbonate in water (0.2 mL) and heated to 65° C. for 18 hours. The mixture was diluted with DCM and quenched with saturated aqueous NaHCO3. The aqueous layer was extracted with DCM three times. The combined organic layers were dried and concentrated. The residue was purified by silica gel column chromatography eluting with 0 to 5% MeOH in EtOAc to give the title compound (28 mg, 68%).
