Procedure

To a solution of N—((S)-2-((3S,5R,6S)-3-allyl-5-(3-chlorophenyl)-6-(4-chlorophenyl)-3-methyl-2-oxopiperidin-1-yl)butyl)-3-chloropropane-1-sulfonamide prepared above in Step A (36.1 mg, 0.062 mmol) in DMF (1.2 mL) was added DBU (46.4 μL, 0.308 mmol) at rt. After being stirred at rt overnight, the reaction was quenched (10% citric acid), extracted (3×EtOAc), and washed (saturated aq. NaHCO3 and sat. aq. NaCl solution). The combined organic layers were dried (Na2SO4) and concentrated under reduced pressure to provide the title compound as a pale brown film.
