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), 3-methoxypropanoic acid (204.2 μL, 2.174 mmol) and triethylamine (605.9 μL, 4.347 mmol) in CH2Cl2 (10 mL) at room temperature was treated with BOP-Cl (202.7 mg, 2.174 mmol). The mixture was stirred at room temperature for 24 hours. 2M LiOH.H2O in water (3 mL) was then added and stirred for 30 minutes. The precipitate formed was filtered, washed with CH2Cl2 (3×2 mL), and dried to provide N-(5-bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)-3-methoxypropanamide (115 mg, 42% yield) as a solid. 1H NMR (400 MHz, (CD3)2SO) δ 12.05 (br s, 1H), 9.55 (s, 1H), 8.34 (d, 1H), 7.63 (s, 1H), 3.63 (t, 2H), 3.26 (s, 3H), 2.58 (t, 2H); LCMS (APCI+) m/z 317.9 (M+H)+, Retention time=2.57 minutes (Method 2).
