Yield:4318-37-0 91.6%

Reaction Conditions:

with palladium 10% on activated carbon;hydrogen in methanol; under 7500.75 Torr; for 4 h;Solvent;

Steps:

1; 2

Weigh 1-benzyl-4-methyl-1,4-homopiperazine (8.05 g, 39.4 mmol),And measure 50mL of methanol into the reaction flask,Weigh 1.6g of 10% Pd/C into the reaction solution, and pass the hydrogen pressure at 1MPa, and react for 4h. After the reaction is complete, suction filtration, concentrate to dryness under reduced pressure, and then distill under reduced pressure to obtain 4.12g of the product. The rate was 91.6%.
