実験手順

To a solution of 543 mg 4-[(S)-4-benzyloxy-2-({5-[2-((S)-2-cyclobutylcarbamoyl-pyrrolidin-1-yl)-2-oxo-ethoxy]-1-phenyl-1H-pyrazole-3-carbonyl}-amino)-butyryl]-piperazine-1-carboxylic acid ethyl ester in 15 ml ethyl acetate were added 200 mg Pd/C (10%) and the suspension stirred under an atmosphere of hydrogen (1 bar) for 12 h. The reaction mixture was filtrated, washed with ethyl acetate and concentrated. The crude product was purified by preparative HPLC (C18 reverse phase column, elution with a water/MeCN gradient with 0.1% TFA). The fractions containing the product were lyophilized to yield the pure product. Yield: 178 mg MS (ES+): m/e=654.
