실험 절차

A mixture of N-(5-bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)isobutyramide (0.20 g, 0.67 mmol; Example 15, Step A), tert-butyl-trans-4-cyclopropylpiperidin-3-ylcarbamate (0.48 g, 2.00 mmol; Example K) and DIEA (0.35 mL, 2.00 mmol) in n-BuOH (2 mL) was stirred at 146° C. (bath) for 20 hours. The solvent was removed. The residue was dissolved in ethyl acetate (20 mL), washed with water (10 mL), brine (10 mL), dried (sodium sulfate) and concentrated in vacuo. The residue was purified by reverse phase chromatography (Biotage SP4, C-18 25M+, 20-80% CH3CN/water, 25 CV). The product isolated was dissolved in DCM (2 mL), and TFA (0.5 mL) was added. The mixture was stirred at room temperature for 1 hour. The solvent was removed. The residue was dissolved in DCM (1 mL), and 2N HCl in ether (3 mL) was added. The solid formed was collected to give N-(4-(trans-3-amino-4-cyclopropylpiperidin-1-yl)-5-bromo-1H-pyrrolo[2,3-b]pyridin-3-yl)isobutyramide hydrochloride (0.17 g, 52%) as a solid. 1H NMR (400 MHz, D2O) δ 8.21 (s, 1H), 7.26 (s, 1H), 3.81 (m, 1H), 3.48 (m, 1H), 3.38 (m, 1H), 3.11 (m, 2H), 2.60 (m, 1H), 1.88 (m, 1H), 1.82 (m, 1H), 1.52 (m, 1H), 1.16 (m, 1H), 1.07 (t, 6H), 0.77 (m, 1H), 0.39 (m, 1H), 0.14 (m, 1H), 0.11 (m, 1H). LCMS (APCI+) m/z 420 (M+H)+.
