Lithium Hydroxide → N-(5-bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)-5-(trifluoromethyl)picolinamide

Participants

Reaction Steps

TEA (0.61 mL, 4.35 mmol) was added to 5-bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-amine (200 mg, 0.87 mmol, Example 1, Step H), 5-(trifluoromethyl)picolinic acid (200 mg, 1.04 mmol) and BOP-Cl (330 mg, 1.30 mmol) in DCM (5 mL). The reaction was stirred at room temperature for 1 hour, and then a LiOH solution (3 mL, 2N) was added. The mixture was stirred for 30 minutes, and water (10 mL) was added. The solid formed was collected by filtration, washed with DCM (10 mL) and dried to give N-(5-bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)-5-(trifluoromethyl)picolinamide (195 mg, 55% yield) as a solid.
