실험 절차

To a solution of 0.325 g (0.73 mmol) of (5R,6S)-5-(3-chlorophenyl)-6-(4-chlorophenyl)-1-((S)-1-(cyclopropylmethoxy)butan-2-yl)piperidin-2-one (Example 68, Step B) and iodomethane (0.055 mL, 0.874 mmol) in THF (7.0 mL) was added lithium bis(trimethylsilyl)amide (1M solution in THF, 0.8 mL, 0.8 mmol) at −78° C. The reaction was allowed to warm to R.T., then was quenched with sat. aqueous NH4Cl solution and extracted with EtOAc. The combined organic layers were washed with water and sat. aq. NaCl solution, dried over MgSO4, filtered and the filtrate was concentrated under reduced pressure.
