Reaction Steps

To a solution of tert-butyl 2-((2-(5-chloro-1H-pyrrolo[2,3-b]pyridin-3-yl)-5-fluoropyrimidin-4-ylamino)methyl)-4,4-difluoropiperidine-1-carboxylate, 13k, (0.09 g, 0.18 mmol) in 2-propanol (2 mL) was added propan-2-ol hydrochloride (2 mL of 6 M, 12.00 mmol). After stirring the reaction mixture at room temperature for 17 hours, an additional 1 mL of IPA/HCl was added and the reaction mixture was heated at 45° C. for 1 hour. All volatiles were removed at reduced pressure and the residue was used directly in the next step without further purification.
