5-Bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-amine (0.5 g, 2.17 mmol; Example 1, Step H), (S)-2-methoxypropanamide (0.471 g, 4.56 mmol), BOP-Cl (1.16 g, 4.56 mmol), and triethylamine (1.51 mL, 10.9 mmol) were placed in DCM (10 mL) and stirred for 18 hours at room temperature, then poured into water, and extracted with DCM. The combined organic fractions were dried (MgSO4), filtered, and concentrated to give the crude product, which was purified by reverse phase chromatography (Biotage SP4, C-18 25M+, 5-95% CH3CN/water) to give (S)-N-(5-bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)-2-methoxypropanamide (0.6 g, 87% yield).
