実験手順

To a solution of 4.4 g 4-((S)-4-tert-Butoxycarbonyl-2-{[5-(3,3-dimethyl-2-oxo-butoxy)-1-phenyl-1H-pyrazole-3-carbonyl]-amino}-butyryl)-piperazine-1-carboxylic acid benzyl ester in 40 ml ethanol were added 0.9 g Pd/C (10%) and the suspension stirred under an atmosphere of hydrogen (3 bar) for 24 h. It was filtrated, washed with ethanol and the solvent evaporated to give the title compound as colorless oil (4.1 g).
