Reaction Steps

To a solution of CH3PPh3Br (863.9 mg 2.42 mmol) in THF (8 mL) was added n-BuLi (0.678 ml, 1.69 mmol) at −78° C. under N2. The mixture was stirred at rt for 1 h, a solution of (R)-1-((S)-1-(4-bromophenyl)ethyl)-4-(2-oxopropyl)-4-phenylpiperidin-2-one (100 mg 0.24 mmol) in THF (5 mL) was added, and the mixture was stirred at reflux overnight. The reaction was quenched by satd aq NH4Cl and extracted with EtOAc. The combined organic phase was dried and concentrated to give the crude product, which was purified by preparative TLC to give (S)-1-((S)-1-(4-bromophenyl)ethyl)-4-(2-methylallyl)-4-phenylpiperidin-2-one (60 mg, 60%).
