To a solution of tert-butyl 3-(cyanomethyl)-3-[4-(5-fluoro-1-{[2-(trimethylsilyl)ethoxy]methyl}-1H-pyrrolo[2,3-b]pyridin-4-yl)-1H-pyrazol-1-yl]azetidine-1-carboxylate (3.05 g, 5.79 mmol) in THF (40 mL) was added a 4.0 M solution of hydrogen chloride in 1,4-dioxane (70 mL, 280 mmol). The mixture was stirred at room temperature for 2 hours and concentrated to give 3.08 g (99.2%) of {3-[4-(5-fluoro-1-{[2-(trimethylsilyl)ethoxy]methyl}-1H-pyrrolo[2,3-b]pyridin-4-yl)-1H-pyrazol-1-yl]azetidin-3-yl}acetonitrile.2[HCl] as a yellowish solid. LC/MS found: 427.2 (M+H)+.
