Reaktionsschritte
To a solution of 2-chloro-1-[4-(4-fluoro-benzyl)-(2R,5S)-2,5-dimethyl-piperazin-1-yl]-ethanone (1.0 g, 3.35 mmol) in butanone (35 mL) was added 2-nitro-4-chlorophenol (0.64 g, 3.69 mmol), potassium carbonate (0.93 g, 6.7mmol) and potassium iodide (0.56 g, 3.35 mmol). The reaction mixture was heated at reflux overnight. The reaction mixture was then cooled, diluted with water and extracted with ethyl acetate. The organic layer was dried over magnesium sulfate, filtered and concentrated to give an orange oil. Chromatography on silica gel gave the title compound (1.35 g).
