Trifluoroacetic acid → N-[(S)-2-hydroxy-1-(2-hydroxyethylcarbamoyl)ethyl]-4-methoxy-3-[(E)-2-(4-trifluoromethoxyphenyl)vinyl]benzamide

Participants

Reaction Steps

Trifluoroacetic acid (1 mL) was added to 20 mg of N-[(S)-2-t-butoxy-1-(2-hydroxyethylcarbamoyl)ethyl]-4-methoxy-3-[(E)-2-(4-trifluoromethoxyphenyl)vinyl]-benzamide and the mixture was stirred for 20 minutes at room temperature. After removal of the solvent, the resulting residue was purified using a micromass spectrometer (ZMD produced by Micromass) equipped with a gradient high-performance liquid chromatograph 996-600E produced by Waters. The resulting solid was dried under reduced pressure to obtain 9 mg (57%) of N—[(S)-2-hydroxy-1-(2-hydroxyethylcarbamoyl)ethyl]-4-methoxy-3-[(E)-2-(4-trifluoromethoxyphenyl)vinyl]benzamide.
