Triethylamine → N-(5-bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)-1-methylcyclopropanecarboxamide

Participants

Reaction Steps

1-Methylcyclopropanecarboxylic acid (435 mg, 4.35 mmol), bis(2-oxooxazolidin-3-yl)phosphinic chloride (553 mg, 2.17 mmol) and triethylamine (1100 mg, 10.9 mmol) were added to 5-bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-amine (500 mg, 2.17 mmol) in DCM (100 mL). The reaction was stirred at room temperature for 1 hour, and then 2N aqueous Na2CO3 was added (50 mL). The resulting suspension was filtered, and the solid was rinsed with DCM and water. After drying, N-(5-bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)-1-methylcyclopropanecarboxamide (464 mg, 68.4% yield) was obtained as a solid.
