(4-Bromobutoxy)benzene → 1-(2-Phenoxyethyl)piperazine

Participants

Reaction Steps

The procedure of Example 2 was repeated in entirety substituting 57.0 g (0.27 moles) of 2-bromoethyl phenyl ether for 4-phenoxybutyl bromide, using 61.6 g (0.54 moles) of 1-formylpiperazine in 300 ml of 2-propanol and refluxing the mixture for 8 hours. Evaporation of the final dried chloroform extracts gave 35 g of 1-[2-phenoxyethyl]piperazine as an oil.
