To a solution of benzyl 4-(trans-4-cyclohexylcyclohexyl)-1-piperazinecarboxylate (4 g) in ethanol (40 ml) and dioxane (40 ml) was added 10% palladium on carbon (0.8 g), and hydrogen gas at atmosphere pressure for 7 hours. To the reaction mixture was added dichloromethane (40 ml). The reaction mixture was filtered, and the filtrate was concentrated by evaporation under reduced pressure to give 1-(trans-4-cyclohexylcyclohexyl)piperazine (1.56 g).
