To a solution of 6-[6-(1-methyl-2-oxo-1,2,3,4-tetrahydro-quinolin-6-yl)-pyrazin-2-yl]-2,6-diaza-spiro[3.3]heptane-2-carboxylic acid tert-butyl ester (example 28, 0.231 g, 0.53 mmol) in DCM (3 mL) was added TFA (0.605 g, 5.3 mmol) and the reaction mixture was stirred at room temperature over night. The mixture was evaporated several times with toluene and then the residue was purified by reverse phase HPLC on a Gemini-NX column, eluting with a 20 to 98% MeOH—H2O (0.05% TEA) gradient to give the title compound (0.203 g, 99%) as a yellow solid (TFA salt). MS: 336.3 (M+H+).
