Bromine → 4-(4-Bromophenyl)piperidine

Participants

Reaction Steps

A solid mixture comprised of 2.65 g (16.4 mmol) of bromine adsorbed onto 5 g of Al2O3 was combined with a solid mixture of 1.05 g (6.56 mmol) of 4-phenylpiperidine adsorbed onto 5 g of Al2O3 and the combined mixture was stirred at rt for 2 h. The mixture was then put into a filter funnel and was eluted with CH2Cl2: EtOAc, 1:1 then CH2Cl2: MeOH:(2N NH3 in MeOH), 100:4:2 to give 1.0 g of the title compound.
