Participants

Reaction Steps

34.0 g (0.15 mole) of 1-carbomethoxy-4-benzylpiperazine dissolved in 300 ml of ethanol was treated with hydrogen over a palladium catalyst at 40 psi and room-temperature for 24 hours. The catalyst was removed by filtration and the solvent removed under reduced pressure. The residue was distilled, b.p. 70°-75° C. at 1.5 mmHg to give 16.0 g of 1-carbomethoxypiperazine.
