Versuchsvorschrift
To a solution of (S)-3-(4-benzyl-piperazin-1-yl)-pyrrolidine-1-carboxylic acid tert-butyl ester (3.7 g, 10.83 mmol) in EtOH (75 mL) and acetic acid (50 mL) 10% Pd on carbon (0.58 g, 0.54 mmol) was added. The reaction mixture was hydrogenated under 1 atm H2 for 18 hours, filtered through Celite and concentrated in vacuo to afford (S)-3-piperazin-1-yl-pyrrolidine-1-carboxylic acid tert-butyl ester as an orange oil. The product was used without further purification.
