Procedure

(R)-tert-Butyl 1-(5-chloro-3-(cyclopentanecarboxamido)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperidin-3-ylcarbamate (80 mg, 0.17 mmol) was stirred in 4N HCl in IPA (5 mL) at about 30-40° C. for 24 hours. The reaction was concentrated to dryness to yield (R)—N-(4-(3-aminopiperidin-1-yl)-5-chloro-1H-pyrrolo[2,3-b]pyridin-3-yl)cyclopentanecarboxamide hydrochloride (72 mg, 115% yield) as a solid.
