실험 절차

A mixture of 1-[1-(3-bromo-5-chloro-2-methoxy-4-methylphenyl)ethyl]-3-methyl-1H-pyrazolo[3,4-d]pyrimidin-4-amine (first peak from Example 167, step 4 chiral separation, 106 mg, 0.25 mmol), 5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)nicotinonitrile (70.0 mg, 0.31 mmol, from Combi-Blocks Catalog, item # PN-8893), sodium carbonate (43 mg, 0.41 mmol) and [1,1′-bis(diphenylphosphino)ferrocene]-dichloropalladium(II), complex with dichloromethane (1:1) (33 mg, 0.041 mmol) in acetonitrile (2 mL)/water (0.6 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 (95 mg, 87%) was purified by chromatography eluting with CH2Cl2/MeOH (max. MeOH 5%). LCMS calculated for C22H21ClN7O (M+H)+: m/z=434.2; Found: 434.2.
