Procedure

To a solution of (S)-3-((3S,5R,6S)-3-allyl-5-(3-chlorophenyl)-6-(4-chlorophenyl)-3-methyl-2-oxopiperidin-1-yl)pentanal (160 mg, 0.349 mmol; Example 130, Step A) in THF (3.5 mL) was added 0.5 M cyclopropylmagnesium bromide in THF (2.09 mL, 1.05 mmol) at 0° C. Then the reaction was allowed to warm to rt and stirred for 3.5 h. The reaction was quenched (sat NH4Cl solution), extracted (2×EtOAc), and washed (sat. aq. NaCl solution). The combined organic layers were dried (Na2SO4) and concentrated under reduced pressure to provide the title compound as a mixture of two diastereomers. The crude product was used in the next step without further purification.
