Procedure

Triethylamine (1018 μL, 7.462 mmol) was added to an aliquot of (R)-tert-butyl 1-(3-amino-5-chloro-1H-pyrrolo[2,3-b]pyridin-4-yl)piperidin-3-ylcarbamate (390 mg, 1.066 mmol; Example 91, Step A) in NMP (3 mL) at 0° C. under N2 atmosphere. The mixture was treated dropwise with cyclopropanecarbonyl chloride (580.4 μL, 6.396 mmol) and stirred at 0° C. for 1 hour. The reaction mixture was then diluted with CH2Cl2 (4 mL). 2M LiOH.H2O (9 mL) was added, and the mixture was allowed to stir for 24 hours. The mixture was then diluted with 2% MeOH/EtOAc (100 mL) and washed with water (4×20 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 40M+, 15-85% CH3CN/water, 38 CV) to provide (R)-tert-butyl 1-(5-chloro-3-(cyclopropanecarboxamido)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperidin-3-ylcarbamate as a solid.
