Reaction Steps
A solution of 5-bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-amine (200 mg, 0.869 mmol, Example 1, Step H) in pyridine at 0° C. was treated dropwise with 2-ethylbutanoyl chloride (176 mg, 1.30 mmol). After 7 hours, 2M LiOH (5 mL) was added to the mixture and stirring was continued at room temperature for 30 minutes. Water (25 mL) was then added, and the solid formed was filtered, washed with water (3×5 mL) and dried to provide N-(5-bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)-2-ethylbutanamide (235 mg, 82% yield) as a solid. 1H NMR (400 MHz, (CD3)2SO) δ 12.06 (s, 1H), 9.46 (s, 1H), 8.34 (d, 1H), 7.53 (s, 1H), 2.30-2.24 (m, 1H), 1.62-1.52 (m, 2H), 1.47-1.41 (m, 2H), 0.90 (t, 6H); LCMS (APCI+) m/z 328, 330 (M+H)+, Retention time=3.20 minutes (Method 2).
