Reaction Steps

To a mixture of 4-(2-thienyl)phenol (1.00 g) and acetic anhydride (869 mg) in tetrahydrofuran (10 ml) was added pyridine (494 mg) with ice-cooling. The mixture was stirred for 1 hour at said temperature and 1 hour at ambient temperature. After concentration, the mixture was partitioned between AcOEt and H2O. The separated organic layer was washed with 1% aqueous citric acid, 3% aqueous NaHCO3 solution and brine, dried over sodium sulfate and concentrated. The residue was triturated with hexane to give 985 mg of 2-(4-acetoxyphenyl)thiophene as a powder.
