Procedure

1-Benzyl-4-(1-phenylcyclohexyl)piperazine (0.47 g) was dissolved in 86 ml methanol and 14 ml 0.2N HCl in methanol. The mixture was hydrogenated over palladium black (0.1175 g) and 3 atm. of hydrogen at room temperature for 1 hour. The reaction was filtered and the solvent was removed in vacuo. The residue was chromatographed on silica gel eluted with the appropriate mixture of methanol and chloroform to yield pure 1-(1-phenylcyclohexyl)piperazine.
