Reaction Steps

2-(Thiophen-2-yl)ethanol (1.05 g) was dissolved in tetrahydrofuran (25 ml), triethylamine (1.63 ml) and methanesulfonyl chloride (725 μl) were added and the mixture was stirred for 20 min. Saturated aqueous sodium hydrogen carbonate (50 ml) was added to the reaction mixture, and the mixture was extracted with diisopropyl ether.
