Reaction Steps

(R)-tert-Butyl 1-(5-bromo-3-(cyclopropanecarboxamido)-1H-pyrrolo [2,3-b]pyridin-4-yl)piperidin-3-ylcarbamate (150 mg, 0.314 mmol; Example 29, Step B), (9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine) (18.1 mg, 0.0314 mmol), Pd2 dba3 (14.4 mg, 0.0157 mmol), propane-2-thiol (71.6 mg, 0.941 mmol), and N-ethyl-N-isopropylpropan-2-amine (109 μL, 0.627 mmol) were placed in dioxane (1 mL) and heated to 150° C. under microwave irradiation for 2 hours. DCM and water were then added to the reaction mixture. The layers were separated, and the organic was washed with 1M NaOH. The organic layer was dried, filtered, and concentrated. The residue was purified by reverse phase chromatography (Biotage SP4, C-18 25M+, 5-95% CH3CN/water). The product was then dissolved in TFA (2 mL) and stirred for 15 minutes. The reaction was concentrated, and the resulting residue was dissolved in 10% MeOH in DCM and then added dropwise to a stirred solution of 2M HCl in ether. The reaction was concentrated to provide (R)-N-(4-(3-aminopiperidin-1-yl)-5-(isopropylthio)-1H-pyrrolo[2,3-b]pyridin-3-yl)cyclopropane carboxamide hydrochloride (72 mg, 51% yield) as a solid. 1H NMR (400 MHz, D2O) δ 8.21 (s, 1H), 7.27 (s, 1H), 3.91 (d, 1H), 3.65 (m, 1H), 3.52 (d, 1H), 3.27-3.09 (m, 3H), 2.15 (m, 1H), 1.81-1.70 (m, 3H), 1.57 (m, 1H), 1.08 (dd, 6H), 0.94-0.80 (m, 4H). LCMS (APCI+) m/z 374.1 (M+H)+, Retention time=2.38 minutes (Method 3).
