To a solution of methyl 2-((3R,5R,6S)-5-(3-chlorophenyl)-6-(4-chlorophenyl)-1-((S)-1-hydroxybutan-2-yl)-3-methyl-2-oxopiperidin-3-yl)acetate (214.4 mg, 0.448 mmol; Example 186, Step A) in toluene (2.0 mL) was added benzyl mercaptan (0.106 mL, 0.90 mmol), followed by cyanomethylenetributylphosphorane (0.235 mL, 0.896 mmol; TCI). The solution was heated at 100° C. for 3.75 hours, then concentrated in vacuo. Purification of the residue by chromatography on silica gel (12 g SiO2, 0% to 50% EtOAc in hexanes) provided the title compound as colorless oil.
