Reaction Steps

5-Nitrothiophene-2-carbonitrile (0.80 g, 5.2 mmol), phenol (1.0 g, 10.4 mmol) and potassium carbonate (2.2 g, 15.6 mmol) were suspended in dimethylsulfoxide (30 mL), and the mixture was stirred at room temperature for 15.5 hours. Water and ethyl acetate were added for partitioning, and the organic layer was washed three times with water. NH silica gel was added to the organic layer, the solvent was evaporated in vacuo for adsorption, purification was carried out by NH silica gel column chromatography (hexane:ethyl acetate=8:1), and 5-phenoxythiophene-2-carbonitrile (720 mg, 3.6 mmol, 69.2%) was obtained as a colorless oil.
