Versuchsvorschrift
In analogy to the procedure described in example 253e, (2S,4R)-1-(2-cyclobutyl-5-cyclopropyl-2H-pyrazol-3-yl)-4-(2-trifluoromethyl-benzenesulfonyl)-pyrrolidine-2-carboxylic acid methyl ester was saponified in the presence of lithium hydroxide to give the title compound as yellow solid which was used in the next step without further purification.
