5-Vinylthiophene-3-sulfonic acid[2-(4-fluorophenyl)ethyl]-methyl-amide → 5-Formylthiophene-3-sulfonic acid [2-(4-fluorophenyl)ethyl]-methyl-amide

Participants

Reaction Steps

To a solution of 5-vinylthiophene-3-sulfonic acid[2-(4-fluorophenyl)ethyl]-methyl-amide (328 mg) in dichloromethane (2 mL) was added sodium meta periodate (863 mg) and ruthenium trichloride monohydrate (5 mg) at room temperature. After stirring for 2 hours, this solution was diluted with water and ethyl acetate, and Celite filtration was carried out. The organic layer was separated, after drying with anhydrous sodium sulfate, the residue that was obtained upon removing the solvent by evaporation were purified by silica gel column chromatography (hexane/ethyl acetate) and the title compound (138 mg) was obtained as a yellow oily substance.
