Reaction Steps

To a solution of 2.32 g 4-[(S)-2-({5-[2-(3-benzyloxycarbonyl-pyrrolidin-1-yl)-2-oxo-ethoxy]-1-phenyl-1H-pyrazole-3-carbonyl}-amino)-4-tert-butoxycarbonyl-butyryl]-piperazine-1-carboxylic acid ethyl ester in 50 ml ethyl acetate was added 1.0 g Pd/C (10%) and the suspension stirred under an atmosphere of hydrogen (3 bar) for 24 h. The reaction mixture was filtrated over a plug of Celite, washed with ethyl acetate and concentrated.
