To a solution of (3S,5R,6S)-3-allyl-5-(3-chlorophenyl)-6-(4-chlorophenyl)-3-ethyl-1-((S)-1-hydroxybutan-2-yl)piperidin-2-one (300 mg, 0.652 mmol) (Example 202, Step B) in DCM (6 mL) was added triethylamine (270 μl, 1.955 mmol) and methanesulfonic anhydride (170 mg, 0.977 mmol) successively at 0° C. The reaction was allowed to warm to rt. After being stirred at rt for 2 h, the reaction was quenched with 10% aq. citric acid, extracted with DCM and the combined extracts were washed with water, dried over Na2SO4, filtered and the filtrate was and concentrated to give the title compound.
