Versuchsvorschrift

To a solution of 5-bromothiophene-2-sulfonic acid methyl-amide (608 mg) in tetrahydrofuran (5 mL) was added 60% sodium hydride (115 mg). After stirring for 20 minutes, 2-bromo-1-(4-fluorophenyl)ethanone (630 mg) was added. After adding water and ethyl acetate, and washing the organic layer with saturated sodium chloride water, this solution was dried with anhydrous sodium sulfate. The residue that was obtained upon removing the solvent by evaporation was purified by silica gel column chromatography (hexane/ethyl acetate) and the title compound (464 mg) was obtained as a yellow oily substance.
