Procedure

253 mg (0.53 mmol) of 5-[4-(5-fluoro-2-methoxyphenyl)-2-hydroxy-4-methyl-2-trifluoromethylpentylidenamino]quinoline-2-carboxylic acid amide is dissolved in 10 ml of tetrahydrofuran-methanol (50%) and mixed with 101 mg (2.65 mmol) of sodium borohydride. After 20 hours, the solvent is removed in a vacuum. The subsequent recrystallization of the residue from ethyl acetate-methanol and purification of the mother liquor that is concentrated by evaporation on silica gel with hexane-ethyl acetate (0–50%) yield 116 mg (46% of theory) of the product.
