실험 절차

To a solution of 2-{2-[7-chloro-2-oxo-6-(3-pyridin-4-yl-ureido)-3-thiophen-2-yl-1,2-dihydroquinolin-4-yloxy]-ethyl }-piperidine-1-carboxylic acid tert-butyl ester in methylene chloride is added trifluoroacetic acid and the mixture stirred at room temperature. After 30 minutes, the mixture is concentrated in vacuo, resolvated in 10% ammonium hydroxide in methanol and concentrated once again. Purification by flash chromatography on silica gel gives the title compound.
