Procedure

Cyclopropylmagnesium bromide (0.5 M solution in THF, 2.0 mL, 1.013 mmol) was added dropwise via syringe over a period of 1 min to a stirred solution of (S)-2-((3S,5R,6S)-3-allyl-5-(3-chlorophenyl)-6-(4-chlorophenyl)-3-methyl-2-oxopiperidin-1-yl)butanal (Example 91, Step C, 150 mg, 0.338 mmol) in THF (1.7 mL) at rt. The reaction mixture was stirred at rt for 20 minutes and then quenched with NH4Cl (30 mL, saturated aqueous solution) and diluted with EtOAc (50 mL). The organic layer was dried over MgSO4, filtered and evaporated in vacuo. Purification by column chromatography (24 g SiO2, Hexanes:EtOAc, 1:0 to 4:1) gave the title compound as a mixture of diastereomers.
