Procedure

To a solution of (3S,5R,6S)-3-allyl-5-(3-chlorophenyl)-6-(4-chlorophenyl)-1-((S)-1-hydroxybutan-2-yl)-3-methylpiperidin-2-one (180 mg, 0.403 mmol; Example 91, Step B) in 2 mL of toluene was added cyanomethylenetributylphosphorane (324 uL, 1.21 mmol) and benzenethiol (121 μL 1.21 mmol) at RT. The mixture was heated to 110° C. for 2 h. The reaction was cooled down, quenched (sat. aq. NH4Cl solution), extracted (2×EtOAc), and washed with brine. The combined organic layers were dried over Na2SO4, filtered and the filtrate was concentrated under reduced pressure. Purification of the residue by chromatography on silica gel (4 g SiO2, 10, 20, 40% EtOAc/hexane) provided the title compound.
