Procedure
To a stirred solution of 6-hydroxyindan-1-one (1.48 g, 10 mmol) in 30 ml of DMF was added 3-chloro-4-fluorobenzotrifluoride (2.46 g, 12 mmol) and cesium carbonate (8.40 g, 25 mmol). The reaction mixture was heated at 80° C. for 12 h. After cooling to room temperature, the reaction mixture was diluted with ethyl acetate, washed with water (2×) and brine, dried over sodium sulfate, filtered and concentrated. The crude product was purified by silica gel chromatography, eluting with ethyl acetate (2-40%) in hexane. The final product was collected as brownish yellow oil.
