To a microwave vial was added 1-[1-(3-bromo-5-chloro-2-methoxy-4-methylphenyl)ethyl]-3-methyl-1H-pyrazolo[3,4-d]pyrimidin-4-amine (15 mg, 0.037 mmol, from peak 1 from Example 167, step 4), potassium cyclopropyltrifluoroborate (8 mg, 0.06 mmol, from Frontier Scientific, item # C10298), potassium phosphate (23 mg, 0.11 mmol), and tetrakis(triphenylphosphine)palladium (4.2 mg, 0.0036 mmol) and then toluene (0.3 mL)/water (0.1 mL). The vial was sealed and degassed with N2 three times. The reaction was heat at 110° C. for 20 h. The crude was purified using RP-HPLC (XBridge C18 column, eluting with a gradient of acetonitrile/water containing 0.1% ammonium hydroxide, at flow rate of 30 mL/min) to give the desired product (1.1 mg, 8%). The product was isolated as a single enantiomer. LCMS calculated for C19H23ClN5O (M+H)+: m/z=372.2; Found: 372.2.
