Versuchsvorschrift

151 mg (0.269 mmol) of tert-butyl 1-[(4-chloro-3-{[(2S,3R)-2-(4-chlorophenyl)-4,4,4-trifluoro-3-methylbutanoyl]amino}phenyl)(methoxy)methyl]cyclopropanecarboxylate (as diastereomer mixture) were dissolved in 2.9 ml of dichloromethane, and 1.0 ml of TFA was added at RT. After 30 min at RT, the reaction mixture was concentrated under reduced pressure and the residue was concentrated under reduced pressure. The crude product obtained in this manner was purified by RP-HPLC (mobile phase acetonitrile/water). This gave 87 mg (64% of theory) of the target compound.
