Versuchsvorschrift
To a solution of tert-butyl (6S)-6-(3,5-difluorophenyl)-3,3-diethylpiperidin-2-one-1-carboxylate from Step D (1.22 g, 3.32 mmol) in CH2Cl2 (7 mL) at ambient temperature was added TFA (3 mL). After stirring for 1.5 h, the reaction mixture was concentrated in vacuo. The residue was partitioned between CH2Cl2 (30 mL) and saturated NaHCO3 (30 mL). The layers were separated and the aqueous layer was further extracted with CH2Cl2 (2×30 mL). The combined organics were dried over sodium sulfate, filtered and then concentrated in vacuo to provide the title compound, which could be used without further purification. MS: m/z=268 (M+1).
