Procedure

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 (Peak 1 from Example 167, step 4 chiral separation, 35 mg, 0.085 mmol), potassium (3-tert-butoxy-3-oxopropyl)trifluoroborane (30.0 mg, 0.13 mmol, from Frontier Scientific, item # P10370), potassium phosphate (54 mg, 0.26 mmol) and tetrakis(triphenylphosphine)palladium(0) (9.8 mg, 0.0085 mmol) and toluene (0.7 mL)/water (0.2 mL). The vial was sealed and degassed with N2 three times. The reaction was heated at 110° C. for 20 h. The crude was filtered and the product (20 mg, 50%) was purified by chromatography eluting with CH2Cl2/MeOH (max. MeOH 6%). LCMS calculated for C23H31ClN5O3 (M+H)+: m/z=460.2; Found: 460.3.
