Procedure

70 mg (0.15 mmol) 5-{[(2-chloro-3-fluoro-4-methoxyphenyl)(2-trifluoromethyl-oxiranyl)methyl]amino}-7-fluoro-1H-quinolin-2-on obtained in example 3 are stirred with 84 mg (0.26 mmol) Caesium carbonate in 0.67 ml ethanol. After 40 hours water is added and the aqueous phase is extracted with ethyl acetate. The combined organic phases are washed with brine and dried over sodium sulphate. After removal of the solvent preparative thin layer chromatography on silica gel (ethyl acetate) yields 22 mg of the title compound.
