Procedure

4-Fluoro-4-(4-fluoro-benzoyl)-piperidine-1-carboxylic acid tert-butyl ester (0.122 g, 0.375 mmol) was solved in dichloromethane (2 mL) and trifluoroacetic acid (0.258 mL, 3.37 mmol) was added at 0° C. Aqueous NaHCO3 was slowly added until pH 9 and the mixture extracted with 3 times with dichloromethane and ethyl acetate. The solvent was evaporated to yield g (0. mmol, 100%) of a white solid that was used without purification on the next steps. MS (m/e): 226.1 (M+H+).
