Procedure

A mixture of 4-amino-1-[1-(3-bromo-5-chloro-2-methoxy-4-methylphenyl)ethyl]-1H-pyrazolo[3,4-d]pyrimidine-3-carbaldehyde (20 mg, 0.047 mmol), {6-[(dimethylamino)carbonyl]pyridin-3-yl}boronic acid (23 mg, 0.12 mmol), sodium carbonate (10 mg, 0.094 mmol) and [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II), complex with dichloromethane (1:1) (7.7 mg, 0.0094 mmol) in acetonitrile (0.3 mL)/ethanol (0.1 mL)/water (0.1 mL) was degassed with N2 and then stirred at 95° C. for 3 h. The mixture was diluted with methylene chloride, washed with sat. NaHCO3, water, brine, dried over Na2SO4, filtered and concentrated. The product was purified by chromatography eluting with CH2Cl2/MeOH (max. MeOH 6%). LCMS calculated for C24H25ClN7O3 (M+H)+: m/z=494.2; Found: 494.1
