A mixture of 3-iodo-1-((1-phenyl-1H-benzo[d]imidazol-2-yl)methyl)-1H-pyrazolo[3,4-d]pyrimidin-4-amine 141 (1.5 g, 3.2 mmol), 3-fluoro-4-hydroxyphenylboronic acid (0.6 g, 3.8 mmol), Pd(dppf)Cl2 (0.3 g) and CsF (1.0 g, 6.4 mmol) in DME (30 mL) and H2O (3 mL) was refluxed overnight. Then the mixture was cooled to room temperature, added H2O (50 mL) and extracted with EtOAc (30 mL×3). The combined organic layers were washed with brine and concentrated in vacuo. The residue was treated with CH2Cl2 and filtered to give 155 (500 mg, yield 34%) as a white solid. LCMS (ESI), M+H+=450.16. 1HNMR (400 MHz, DMSO) δ 5.875 (s, 2H), 7.046-7.120 (m, 2H), 7.175-7.200 (d, J=1.6 Hz, 1H), 7.242-7.307 (m, 3H), 7.432-7.472 (m, 5H), 7.687-7.708 (d, J=1.2 Hz, 1H), 8.335 (s, 1H)
