実験手順
A suspension of 4-((S)-2-benzyloxycarbonylamino-4-tert-butoxycarbonyl-butyryl)-piperazine-1-carboxylic acid butyl ester (4.00 g, prepared as described in WO2008050301) and Pd/C (5%, 0.42 g) in EtOH (15 mL) was hydrogenated at RT overnight. The reaction mixture was then stirred under H2 overnight. The mixture was filtered through celite and evaporated off. HV drying afforded the desired compound as light brown oil (2.79 g).
