Reaction Steps

To a solution of tert-butyl 4-{3-(cyanomethyl)-3-[3-(7-{[2-(trimethylsilyl)ethoxy]methyl}-7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1H-pyrrol-1-yl]azetidin-1-yl}piperidine-1-carboxylate (3.3 g, 5.6 mmol) in THF (17 mL) was added a 4 N solution of HCl in dioxane (17 mL). The mixture was stirred at room temperature for 2 hours and concentrated to afford {1-piperidin-4-yl-3-[3-(7-{[2-(trimethylsilyl)ethoxy]methyl}-7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1H-pyrrol-1-yl]azetidin-3-yl}acetonitrile trihydrochloride as a white powder solid, which was used for the next reaction. Yield: 99%; LC-MS: [M+H]+=492.3.
