A 100 mL sealable tube was charged with 1-(4-methoxybenzyl)-4-chloro-3-iodo-1H-pyrazolo[3,4-b]pyridine (0.250 g, 0.626 mmol Example 84, Step D), 2-(3-fluoro-4-hydroxyphenylamino)-N-(4-fluorophenyl)nicotinamide (0.427 g, 1.25 mmol), cesium carbonate (0.408 g, 1.25 mmol), and 1-bromobenzene (6.26 ml, 0.626 mmol). The reaction mixture was heated to 160° C. for 18 hours. The reaction mixture was cooled to ambient temperature and concentrated. The residue was dissolved in EtOAc and washed with brine. The crude material was purified by silica gel (Biotage 40S) eluting with 4:1 Hexane/EtOAc to provide the product (0.35 g, 71%). LRMS M−1 (704.9) observed.
