1-benzyl-4-(2-methylphenyl)piperazine-2-carboxamide (2.64 g, 8.53 mmol) and palladium hydroxide/carbon (430 mg) were combined in a mixture of methanol (35 ml) and ethanol (35 ml) and shaken in an atmosphere of hydrogen at 55 psi for 6 hours at ambient temperature. The mixture was filtered and the filtrate was concentrated in vacuo. The residue was reconcentrated in vacuo from ether three times to provide 4-(2-methylphenyl)piperazine-2-carboxamide.
