A solution of N—((S)-2-((3S,5R,6S)-3-allyl-5-(3-chlorophenyl)-6-(4-chlorophenyl)-2-oxo-3-((2-(trimethylsilyl)ethoxy)methyl)piperidin-1-yl)butyl)cyclopropanesulfonamide (Example 414, Step C, 1.5 g, 2.253 mmol) in THF was treated with sodium hydride (60% dispersion in mineral oil, 6.76 mmol) and iodomethane (0.280 ml, 4.51 mmol) at room temperature for 3 hours. The reaction mixture was quenched with HCl (1N) and diluted with DCM. The organic extract was washed with satd NaCl and dried over Na2SO4. The solution was filtered and concentrated in vacuo to give the crude material as an oil. The product was purified by chromatography through a RediSep® pre-packed silica gel column (Teledyne Isco, Lincoln, Nebr.) (4 g), eluting with a gradient of 0% to 80% EtOAc in hexane, to provide the title compound as an oil.
