4-(1-(4-Methoxybenzyl)-3-iodo-1H-pyrazolo[3,4-b]pyridin-4-yloxy)-3-fluorobenzenamine (0.490 g, 1.0 mmol, prepared according to Example 7, Step B) and acetonitrile (5 mL) were heated with 1-((4-fluorophenyl)carbamoyl)-cyclopropanecarbonyl fluoride (0.450 g, 2.00 mmol, prepared according to Example 6, Step A) at 100° C. in a sealed vessel for 4 hours. The suspension was allowed to cool to ambient temperature, and then in an ice bath for 15 minutes. The solid was filtered to provide pure desired product (0.52 g, 75%) by LRMS (APCI−): 100% purity, 220 nm, m/z 694 (M−1) detected.
