Reaction Steps
(R)-N-(4-(3-Aminopiperidin-1-yl)-5-bromo-1H-pyrrolo[2,3-b]pyridin-3-yl)cyclopropanecarboxamide hydrochloride (0.112 g, 0.248 mmol; Example 29, Step C), 1-bromo-2-fluoroethane (0.0222 mL, 0.298 mmol) and DIEA (0.173 mL, 0.993 mmol, d 0.742) were placed in DMF (2 mL) and heated to 80° C. for 36 hours. The reaction was then cooled to room temperature, poured into water, and extracted with EtOAc. The combined organic fractions were dried (MgSO4), filtered, and concentrated to give the crude product, which was purified by reverse phase chromatography (Biotage SP4, C-18 40M+, 5-50% water:ACN). The product was next dissolved in minimal DCM (with MeOH to aid solubility) and added to a stirring solution of 1M HCl in ether. The resulting solid was filtered, washed with ether and dried to give (R)-N-(5-bromo-4-(3-(2-fluoroethylamino)piperidin-1-yl)-1H-pyrrolo[2,3-b]pyridin-3-yl)cyclopropanecarboxamide hydrochloride (0.018 g, 15% yield) as a solid. 1H NMR (400 MHz, D2O) δ 8.23 (s, 1H), 7.26 (s, 1H), 4.69-4.67 (m, 1H), 4.56-4.55 (m, 1H), 3.84-3.81 (m, 1H), 3.57-3.54 (m, 1H), 3.42-3.16 (m, 5H), 2.22-2.19 (m, 1H), 1.80-1.73 (m, 3H), 1.57-1.55 (m, 1H), 0.90-0.80 (m, 4H). LCMS (APCI+) m/z 424, 426 (M+H)+.
