Procedure
4,4-Diethoxy-1-(1-(S)-phenyl-ethyl)-2-(S)-phthalimidomethyl-piperidine (4.0 g, 9.2 mmol) was dissolved in a mixture of trifluoroacetic acid/water (9:1) (100 ml) at 0° C. and stirred for 2 hours at this temperature. The mixture was basified with half saturated aqueous sodium carbonate, extracted with ethyl acetate and dried (MgSO4) for 2 hours and filtered. The solvent was removed in vacuo and the residue was left in a vacuum own at 40° C. for two days, which afforded 3.23 g (98%) of 4-oxo-1-((S)-1-phenyl-ethyl)-2-(S)-phthalimidomethyl-piperidine as a solid.
