Reaction Conditions

Reaction Steps

To a solution of 5-nitrothiophene-2-carbonitrile (1.79 g, 11.6 mmol) and 3-bromophenol (2.00 g, 11.6 mmol) in dimethylsulfoxide (22 mL) was added potassium carbonate (1.76 g, 12.8 mmol), and the solution was stirred at 70° C. for 3 hours. The reaction solution was allowed to room temperature, ethyl acetate and water were added for partitioning, the organic layer was washed with brine and dried over anhydrous magnesium sulfate. The solvent was evaporated, the residue was purified by silica gel column chromatography (hexane:ethyl acetate=10:1), and 5-(3-bromophenoxy)-thiophene-2-carbonitrile (2.00 g, 62%) was obtained as a yellow oil.
