Procedure

To a solution of (3R,5R,6S)-5-(3-chlorophenyl)-6-(4-chlorophenyl)-1-(cyclopent-2-enyl)-3-((2,2-dimethyl-1,3-dioxolan-4-yl)methyl)-3-methylpiperidin-2-one (Example 28, Step C) (310 mg, 0.603 mmol) in THF (3 mL) at room temperature was added aq. HCl (1 M) (3013 μL, 3.01 mmol). The reaction mixture was stirred at room temperature for 19 h. The reaction mixture was diluted with EtOAc and the layers were separated. The organic layer was washed with sat. NaHCO3, sat. aq. NaCl solution and dried over Na2SO4 and concentrated under reduced pressure to provide the title compound.
