206.7 mg Crude 5-[2-(4-{1-[(tert-butoxycarbonyl)amino]cyclobutyl}phenyl)-3-phenylpyrimido[1,2-b]indazol-8-yl]pyrazole-1-carboxylic acid tert-butyl ester, intermediate example Int-3-0, were dissolved in 15 mL 4 M hydrogen chloride in dioxane. The reaction mixture was stirred over night at room temperature. After evaporation of the solvent the residue was dissolved in methanol and given on a PoraPak Rxn CX column. The column was washed with 100 mL methanol, and the product was eluted with methanol/ammonia. The solvent was removed, and the residue was purified by HPLC yielding 32.8 mg of the title compound.
