Versuchsvorschrift

To a solution of 2-{2-[7-chloro-3-(3,5-dimethylphenyl)-6-(3-methyl-2,5-dioxoimidazolidin-1-yl)-2-oxo-1,2-dihydroquinolin-4-yloxy]-ethyl}-piperidine-1-carboxylic acid tert-butyl ester in 2.0 dry methylene chloride was added a few drops of anisole followed by 1.0 mL of trifluoroacetic acid and the mixture stirred at room temperature. After 1 hour the solvents were removed in vacuo and the resulting residue purified by flash chromatography on silica gel (methylene chloride:ammonium hydroxide:methanol, 96:1:3) to give the title compound.
