Reaction Steps

(R)—N-(4-(3-Aminopiperidin-1-yl)-5-bromo-1H-pyrrolo[2,3-b]pyridin-3-yl)cyclopropanecarboxamide hydrochloride (0.100 g, 0.222 mmol; Example 29, Step C), 1-bromo-2-methoxyethane (0.0246 mL, 0.266 mmol), and DIEA (0.154 mL, 0.887 mmol, d 0.742) were placed in DMF (2 mL) and heated to 80° C. for 18 hours. The reaction was then 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 25M+, 20-50% CH3CN/water). 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-methoxyethylamino)piperidin-1-yl)-1H-pyrrolo[2,3-b]pyridin-3-yl)cyclopropanecarboxamide (0.03 g, 30%). 1H NMR (400 MHz, D2O) δ 8.23 (s, 1H), 7.26 (s, 1H), 3.77-3.74 (m, 1H), 3.54-3.50 (m, 3H), 3.28-3.11 (m, 5H), 3.18 (s, 3H), 2.19-2.12 (m, 1H), 1.82-1.61 (m, 4H), 0.90-0.82 (m, 4H). LCMS (APCI+) m/z 436, 438 (M+H)+.
