A 4.0 M solution of HCl in 1,4-dioxane (4 ml) was added to a solution of 4-[1-benzenesulfonyl-5-(2-cyano-acetylamino)-1H-pyrrolo[2,3-b]pyridin-4-ylamino]-piperidine-1-carboxylic acid tert-butyl ester (1.44 mmol) in 1,4-dioxane (2 ml) at 25° C. The reaction mixture was stirred at 25° C. for 1 h, then was concentrated under reduced pressure to afford crude N-[1-benzenesulfonyl-4-(piperidin-4-ylamino)-1H-pyrrolo[2,3-b]pyridin-5-yl]-2-cyano-acetamide (hydrochloride salt) as a brown solid. This material was used in the next step below without additional purification or characterization.
