A mixture of 6-(2,6-dichloro-3,5-dimethoxyphenyl)-3-iodo-1H-pyrazolo[3,4-d]pyrimidine (18.0 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), 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 120° C. for 3 h. After cooling, the mixture was diluted with methanol, and purified by RP-HPLC (pH=10) to afford the desired product. LCMS (M+H)+=514.0/516.0. 1H NMR (300 MHz, DMSO-d6) δ: 9.77 (s, 1H), 8.02 (s, 1H), 7.92 (d, J=8.4 Hz, 1H), 7.06 (s, 1H), 6.97 (d, J=8.4 Hz, 1H), 5.76 (d, J=9.1, 7.4 Hz, 1H), 3.99 (s, 6H), 3.55-3.49 (m, 2H), 3.13 (s, 3H), 2.90 (s, 3H).
