Procedure

NaH (0.076 g, 1.900 mmol) was added to a solution of (3S,5R,6S)-5-(3-chlorophenyl)-6-(4-chlorophenyl)-3-methyl-3-(methylthiomethyl)piperidin-2-one (Example 88, step E) (0.150 g, 0.380 mmol) in 3-bromopentane (1.42 mL, 11.41 mmol) at rt under nitrogen. The reaction mixture was heated at 120° C. for 24 hours, cooled to rt, diluted with water and extracted with DCM three times. The organics were pooled, washed with sat. aq. NaCl solution, dried (MgSO4), filtered and concentrated in vacuo to provide a yellow oil. Purification using a 24 g SiO2 column and eluting with 15% EtOAc/hexanes provided the title compound as a colorless syrup.
