Reaction Steps
Picolinoyl chloride hydrochloride (501 mg, 2.82 mmol) was added to a solution of 5-bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-amine (324 mg, 1.41 mmol, Example 1, Step H) in pyridine (5 mL). The reaction was stirred at room temperature for 10 minutes, and the pyridine was removed in vacuo. The residue obtained was dissolved in THF (5 mL), treated with 2N LiOH (3 mL), and stirred for 20 minutes. THF was then removed in vacuo, and water (20 mL) was added. The solid formed was collected by filtration and dried to provide N-(5-bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)picolinamide (389 mg, 82% yield) as a solid. 1H NMR (400 MHz, (CD3)2SO) δ 12.17 (br s, 1H), 10.39 (s, 1H), 8.76 (d, 1H), 8.40 (d, 1H), 8.17-8.15 (m, 1H), 8.09 (dt, 1H), 7.87 (d, 1H), 7.71-7.68 (m, 1H).
