Procedure

5-Bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-amine (200 mg, 0.869 mmol, Example 1, Step H), 2-methylnicotinic acid (250 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 90 minutes. 3M LiOH (5 mL) was added. The reaction was stirred for 20 minutes and then was poured onto water. The mixture was then filtered and washed with water and DCM. The filtered solid was dried to give N-(5-bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)-2-methylnicotinamide (254 mg, 84% yield).
