Reaction Steps
A mixture of 1-[1-(3-bromo-5-chloro-2-ethoxy-4-methylphenyl)ethyl]-3-methyl-1H-pyrazolo[3,4-d]pyrimidin-4-amine (70 mg, 0.16 mmol) (first peak from Example 195, step 4), tert-butyl [4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazol-1-yl]acetate (65 mg, 0.21 mmol), sodium carbonate (30.0 mg, 0.28 mmol) and [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II), complex with dichloromethane (1:1) (23 mg, 0.028 mmol) in acetonitrile (3 mL)/water (0.7 mL) was degassed with N2 and then stirred at 95° C. for 2 h. The mixture was diluted with methylene chloride, washed with sat. NaHCO3, water, brine, dried over Na2SO4, filtered and concentrated. The product (65 mg, 78%) was purified by chromatography eluting with CH2Cl2/MeOH (max. MeOH 5%). LCMS calculated for C26H33ClN7O3 (M+H)+: m/z=526.2; Found: 526.3.
