Procedure

To a mixture of 4-(2-thienyl)phenol (1.76 g) and triethylamine (1.50 g) in MeCN (10 ml) was added dropwise methanesulfonylchloride (1.26 g) with ice-cooling. The mixture was stirred for 1 hour, then for 1 hour at ambient temperature. The resulting mixture was concentrated and diluted with a mixture of AcOEt and H2O to separate solid. The separated solid was recovered and washed with H2O and AcOEt to give 1.62 g of 2-(4-methanesulfonyloxyphenyl)thiophene.
