A solution of 5-bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-amine (200 mg, 0.869 mmol, Example 1, Step H), 3-chloro-4-fluorobenzoic acid (319 mg, 1.83 mmol), BOP-Cl (465 mg, 1.83 mmol), and triethylamine (0.606 mL, 4.35 mmol) in DCM (5 mL) at room temperature was stirred for 2 hours. 3M aqueous LiOH (3 mL) was then added, and the mixture was stirred for 10 minutes. Next, water (10 mL) and DCM (10 mL) were added, and the resulting precipitate was filtered. The solid isolated was triturated with 10:1 CH2Cl2:MeOH and filtered to provide N-(5-bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)-3-chloro-4-fluorobenzamide (240 mg, 71% yield) as a solid.
