Procedure
To a solution of 3.2 g Piperazine-1,4-dicarboxylic acid benzyl ester 3,3,3-trifluoro-propyl ester in 60 ml ethanol were added 200 mg Pd/C (10%) and the suspension stirred under an atmosphere of hydrogen (3 bar) for 12 h. The reaction mixture was filtrated over a plug of Celite®, washed with ethanol and concentrated. Yield: 2.0 g colorless oil.
