Reaction Steps

A 100 mL round-bottomed flask was charged with 6-(1-(4-methoxybenzyl)-3-methyl-1H-pyrazolo[3,4-b]pyridin-4-yloxy)pyridin-3-amine (0.500 g, 1.38 mmol), 1-((4-fluorophenyl)carbamoyl)cyclopropanecarbonyl fluoride (0.545 g, 2.42 mmol; prepared as in Example 6, Step A), and DMF (10 mL). DIEA (0.723 mL, 4.15 mmol) was added under nitrogen and the reaction mixture was heated at 50° C. for 18 hours. The reaction mixture was cooled to room temperature, diluted with water (100 mL), and extracted with EtOAc (50 mL). The organic layer was dried over sodium sulfate, filtered and concentrated to provide the crude product (1.55 g, 59%). LRMS (esi+) 567 (M+H).
