Tetrahydrofuran → (2s,5s)-1-Allyl-4-(4-bromo-alpha-(3-(tert-butyldimethylsilyloxy)phenyl)benzyl)-2,5-dimethylpiperazine

Participants

Reaction Steps

The purified benzhydrylpiperazine (1.51 g, 3.1 mmol) was dissolved in 20 mL of dry tetrahydrofuran with 0.27 mL (3.2 mmol) of alkyl bromide and 1.6 g (15.5 mmol) of sodium carbonate and heated at reflux overnight under nitrogen. The cooled reaction solution was filtered and the solvent removed to give 1.62 g of crude (2S,5S)-1-allyl-4-(4-bromo-α-(3-(tert-butyldimethylsilyloxy)phenyl)benzyl)-2,5-dimethylpiperazine as a yellow oil.
