Procedure

To a solution of {1-[5-(1H-pyrazol-4-yl)-pyridin-2-yl]-cyclobutyl}-carbamic acid tert-butyl ester (300 mg, 0.96 mmol) in CH2Cl2 (5 mL) was added TFA (0.37 mL, 4.8 mmol). After 15 h, 4M HCl in dioxane (1.2 mL, 4.8 mmol) was added. After 1 h, the reaction was concentrated in-vacuo to yield 303 mg of the title compound, m/z 215.4 [M+H]+.
