Hydrochloric Acid → {3-[4-(1-{[2-(trimethylsilyl)ethoxy]methyl}-1H-pyrrolo[2,3-b]pyridin-4-yl)-1H-pyrazol-1-yl]azetidin-3-yl}acetonitrile

Participants

Reaction Steps

A solution of tert-butyl 3-(cyanomethyl)-3-[4-(1-{[2-(trimethylsilyl)ethoxy]methyl}-1H-pyrrolo[2,3-b]pyridin-4-yl)-1H-pyrazol-1-yl]azetidine-1-carboxylate (341 mg, 0.67 mmol) in THF (5 mL) and methanol (5 mL) was added a 4.0 M solution of hydrogen chloride in 1,4-dioxane (5 mL, 20 mmol). The mixture was stirred at room temperature for 2 hours and concentrated to give 347 mg (100%) of {3-[4-(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: 409.2 (M+H)+.
