Reaction Steps

Di(1H-imidazol-1-yl) methanone (2185 mg, 13.5 mmol) was added to a stirring solution of crude (R)-tert-butyl 1-(3-amino-5-chloro-1H-pyrrolo[2,3-b]pyridin-4-yl)piperidin-3-ylcarbamate (986 mg, 2.70 mmol) in THF (10 mL), and the mixture was stirred at room temperature. After 18 hours, the reaction mixture was concentrated in vacuo. The residue obtained was dissolved in EtOAc (100 mL) and washed with water (4×20 mL) and brine (1×20 mL). The organic layer was separated, dried (MgSO4), filtered, and concentrated in vacuo. The residue obtained was purified by reverse phase chromatography (Biotage SP4, C-18 25M+, 15-85% CH3CN/water). The product was extracted from the aqueous phase into EtOAc (3×50 mL). The combined organic layers were washed with water (2×10 mL), dried (MgSO4), filtered, and concentrated in vacuo to provide (R)-tert-butyl 1-(5-chloro-3-(pyrrolidine-1-carboxamido)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperidin-3-ylcarbamate (920 mg, 74% yield) as a solid. LCMS (APCI+) m/z 463.1 (M+H)+.
