Procedure

A mixture of 1-[1-(3-bromo-5-chloro-2-methoxy-4-methylphenyl)ethyl]-3-methyl-1H-pyrazolo[3,4-d]pyrimidin-4-amine (peak 1 from Example 167, step 4, 322 mg, 0.76 mmol), 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine-2-carbonitrile (210 mg, 0.91 mmol, from Combi-Blocks Catalog, item # PN-0143), sodium carbonate (130 mg, 1.2 mmol) and [1,1′-bis(diphenylphosphino)ferrocene]-dichloropalladium(II), complex with dichloromethane (1:1) (99 mg, 0.12 mmol) in acetonitrile (5 mL)/water (2 mL) was degassed with N2 and the reaction was 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 (0.28 g, 85%) was purified by chromatography eluting with CH2Cl2/MeOH (max. MeOH 6%). LCMS calculated for C22H21ClN7O (M+H)+: m/z=434.1; Found: 434.1
