Versuchsvorschrift

5-Methylnicotinic acid (477 mg, 3.48 mmol), bis(2-oxooxazolidin-3-yl)phosphinic chloride (885 mg, 3.48 mmol) and triethylamine (880 mg, 8.69 mmol) were added to 5-bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-amine (400 mg, 1.74 mmol) in DCM (200 mL). The reaction was stirred at room temperature for 1 hour, and then 3M aqueous LiOH (4 mL) was added. The reaction was stirred for 1 hour, and then saturated aqueous Na2CO3 was added (200 mL). The aqueous phase was extracted once with DCM (200 mL), and then the aqueous phase was filtered. The filtered cake was dried to yield N-(5-bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)-5-methylnicotinamide (228 mg, 37.6% yield) as a solid.
