Procedure

A mixture of 6-(2,6-difluoro-3,5-dimethoxyphenyl)-3-iodo-1H-pyrazolo[3,4-d]pyrimidine (16.7 mg, 0.0400 mmol), N,N-dimethyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2,3-dihydro-1-benzofuran-2-carboxamide (19.0 mg, 0.0600 mmol) (Example 1, Step 2), tetrakis(triphenylphosphine)palladium(0) (2.77 mg, 0.00240 mmol) and sodium carbonate (12.7 mg, 0.120 mmol) in 1,4-dioxane (0.42 mL) and water (0.14 mL) in a reaction vial was sealed, and degassed and recharged with nitrogen for three times. The mixture was stirred at 115° C. for 5 h. After cooling, the mixture was diluted with methanol, and purified by RP-HPLC (pH=10) to afford the desired product. LCMS (M+H)+=482.0.
