Ethyl acetate is added and the mixture is stirred vigorously for 30 minutes. Phases are separated and two times extracted with ethyl acetate. The combined organic phases are concentrated to yield quantitatively 5-{[1-(4-chloro-3-fluoro-2-methoxyphenyl)-3,3,3-trifluoro-2-hydroxy-2-methoxymethylpropylidene]amino}-7-fluoro-1H-quinolin-2-one. The raw imine in 4.2 ml methanol is cooled to 5 C. and 120 mg sodium boron hydride are added in multiple portions over the period of 72 hours. The reaction is quenched by addition of saturated ammonium chloride solution and diluted with water and ethyl acetate. The phases are separated, the aqueous layer 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 (acetone in methylene chloride, 30%) yields 9.5 mg of the title compound.
