Procedure

5-Bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-amine (200 mg, 0.869 mmol, Example 1, Step H), 3-fluorobenzoic acid (256 mg, 1.83 mmol), bis(2-oxooxazolidin-3-yl)phosphinic chloride (465 mg, 1.83 mmol), and triethylamine (0.606 mL, 4.35 mmol) were placed in DCM (5 mL) and stirred at room temperature for 30 minutes. 3M LiOH (3 mL) was then added. The reaction was stirred for 10 minutes and then poured into water. The aqueous layer was extracted several times with DCM, and the combined organic phases were dried, filtered, and concentrated to give N-(5-bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)-3-fluorobenzamide.
