Procedure

To a solution of (3S,5R,6S)-3-allyl-5-(3-chlorophenyl)-6-(4-chlorophenyl)-3-methyl-1-((S)-1-(piperazin-1-yl)butan-2-yl)piperidin-2-one (Example 95, Step B) (60 mg, 0.117 mmol) in DCE (1.2 mL) was added cyclopropanesulfonyl chloride (23.76 μL, 0.233 mmol) followed by diisopropylethylamine (40.6 μL, 0.233 mmol). The reaction mixture was stirred at room temperature for 16 hours, diluted with water (10 mL) and the layers were separated. The aqueous layer was extracted with DCM (2×10 mL). The combined organic layers were washed with saturated NaCl solution (10 mL), dried over sodium sulfate, filtered, and the filtrate concentrated under reduced pressure to afford the title compound as a solid.
