Reaction Steps

A mixture of 5-bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-amine (200 mg, 0.869 mmol, Example 1, Step H), 2-cyclopropylacetic acid (218 mg, 2.17 mmol), triethylamine (606 μL, 4.35 mmol), and BOP-Cl (203 mg, 2.17 mmol) in CH2Cl2 (10 mL) was stirred at room temperature for 42 hours. Then 2M LiOH.H2O (3 mL) was added, and the mixture was stirred for 18 hours. The mixture was then diluted with CH2Cl2 (50 mL). The layers were separated, and the organic layer was dried (MgSO4), filtered, and concentrated in vacuo to provide N-(5-bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)-2-cyclopropylacetamide (204 mg, 75% yield) as a solid. 1H NMR (400 MHz, (CD3)2SO) δ 12.04 (s, 1H), 9.40 (s, 1H), 8.34 (d, 1H), 7.61 (s, 1H), 2.24 (d, 2H), 1.10-1.03 (m, 1H), 0.52-0.47 (m, 2H), 0.24-0.20 (m, 1H); LCMS (APCI+) m/z (M+H)+, Retention time=2.92 minutes (Method 2).
