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 (0.85 g, 1.7 mmol) was dissolved in ethyl acetate (2 mL). To the solution was added 4.0 M hydrogen chloride in 1,4-dioxane (2.0 mL, 8.0 mmol). The mixture was stirred at room temperature for 3 hours. Ether was added, the mixture was centrifuged, and then the solvents were decanted. The residue was dried under vacuum to afford the desired product as HCl salt which was directly used in next step reaction without further purification. LCMS (M+H)+: m/z=409.2
