Procedure

To a solution of tert-butyl 4-{3-(cyanomethyl)-3-[4-(7-{[2-(trimethylsilyl)ethoxy]methyl}-7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1H-pyrazol-1-yl]azetidin-1-yl}piperidine-1-carboxylate (3.2 g, 5.4 mmol) in 10 mL of THF was added 10 mL of 4 N HCl in dioxane. The reaction mixture was stirred at room temperature for 2 hours. Removing solvents under reduced pressure yielded 3.25 g (100%) of {1-piperidin-4-yl-3-[4-(7-{[2-(trimethylsilyl)ethoxy]methyl}-7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1H-pyrazol-1-yl]azetidin-3-yl}acetonitrile trihydrochloride as a white powder solid, which was used directly in the next reaction.
