Procedure

To a solution of ethyl 2-mercaptoacetate (Aldrich, 1.0 mL, 9.1 mmol) in acetonitrile (10.0 mL) were added K2CO3 (2.76 g, 20.0 mmol) and 1-(bromomethyl)-4-fluorobenzene (2.27 g, 12.0 mmol). The mixture was stirred at room temperature for 12 h. After filtration and concentration, the residue was purified by flash column chromatography on SiO2 to give ethyl 2-(4-fluorobenzylthio)acetate (1.89 g, 91% yield). MS(ESI+): m/z 251.08 (M+H)+.
