실험 절차
To a solution of 591 mg 4-(2-Benzyloxycarbonylamino-3-fluoro-butyryl)-piperazine-1-carboxylic acid propyl ester in 20 ml ethanol were added 0.1 g Pd/C (10%) and the suspension stirred under an atmosphere of hydrogen (1 bar) for 1 h. The reaction mixture was filtrated over a plug of Celite, washed with ethanol and concentrated to give the crude product which was used in the subsequent reaction. Yield: 347 mg.
