A solution of tert-butyl 4-[4-(1-{[(E)-(2,6-dichloro-3-fluorophenyl)methylidene]amino}-1H-pyrrolo[3,2-b]pyridin-6-yl)-1H-pyrazol-1-yl]piperidine-1-carboxylate (15 mg, 0.027 mmol) in MeOH (0.5 mL) was treated with HCl (4.0M solution in dioxane, 2.0 mL) at room temperature for 2 h. Solvents were removed and the residue was treated with aqueous NaHCO3, and extracted with ethyl acetate. The organic layer was dried, evaporated to afford the desired intermediate as a yellowish solid (6.5 mg, yield 53%).
