Procedure

By the procedure of Example 149, Step A, (S)-2-((3S,5R,6S)-3-allyl-5-(3-chlorophenyl)-6-(4-chlorophenyl)-3-methyl-2-oxopiperidin-1-yl)-2-cyclopropylacetaldehyde (Example 257, Step C, 866 mg, 1.897 mmol) was treated with methyl magnesium bromide to give the diastereomeric alcohols (3S,5R,6S)-3-allyl-5-(3-chlorophenyl)-6-(4-chlorophenyl)-1-((1S,2R)-1-cyclopropyl-2-hydroxypropyl)-3-methylpiperidin-2-one and (3S,5R,6S)-3-allyl-5-(3-chlorophenyl)-6-(4-chlorophenyl)-1-((1S,2S)-1-cyclopropyl-2-hydroxypropyl)-3-methylpiperidin-2-one as a white foam. MS (ESI) m/z=472 [M+H]+.
