HCID 180010494-Phenyl-1-(4-carboxyphenyl)piperidine

実験手順

To 4-phenyl-1-(4-cyanophenyl)piperidine (0.39 g) are added acetic acid (10 ml) and conc. hydrochloric acid (10 ml), and the mixture is refluxed for five hours. The reaction solution is concentrated, and to the residue is added diethyl ether/methanol. The insoluble crystals are collected by filtration, and dried under reduced pressure to give 4-phenyl-1-(4-carboxyphenyl)piperidine (0.39 g) as white powder.
