실험 절차

To a solution of 260 mg (0.543 mmol) of 2-((3R,5R,6S)-5-(3-chlorophenyl)-6-(4-chlorophenyl)-1-((2S,3S)-2-hydroxypentan-3-yl)-3-methyl-2-oxopiperidin-3-yl)acetic acid (Example 152) in 5 mL of THF was added 60% sodium hydride (217 mg, 5.43 mmol) at 0° C. After being stirred at 0° C. for 20 min, iodomethane (271 uL, 4.35 mmol) was added. The reaction was allowed to warm to ambient temperature, and stirred for an additional 3 h until completion. The reaction was quenched with saturated aqueous NH4Cl solution, extracted with EtOAc (2×25 mL). The combined organic layers were washed with saturated NaCl, dried over MgSO4, filtered and the filtrate was concentrated to provide the title compound.
