Procedure

To a suspension of sodium hydride (19.1 g) in DMSO (200 mL) was added dropwise a solution of thiophen-2-ylacetonitrile (25 g) in DMSO (20 mL) at 0° C. under a nitrogen atmosphere, and the mixture was stirred for 0.5 hr. To the obtained reaction mixture was added dropwise a solution of 1-bromo-2-chloroethane (25 mL) in DMSO (20 mL) at 0° C. under a nitrogen atmosphere, and the mixture was stirred at room temperature for 3 days. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The organic layer was dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound as a pale-brown oil (29.2 g).
