Versuchsvorschrift
To a solution of 1.33 g ({5-[2-((S)-2-Cyclobutylcarbamoyl-pyrrolidin-1-yl)-2-oxo-ethoxy]-1-phenyl-1H-pyrazole-3-carbonyl}-amino)-acetic acid tert-butyl ester in 20 ml dichloromethane were added 3.8 ml TFA. After stirring for 5 h it was concentrated and codistilled twice with toluene to give the crude product. Yield: 1.58 g
