2-(2,2,2-trifluoroethoxy)ethyl p-toluenesulfonate (14.0 g, 47 mmol) and potassium thioacetate (10.0 g, 88 mmol) were dissolved in acetone (100 ml) and the mixture was stirred at room temperature for 2 days. The mixture was poured into water and extracted with ethyl acetate. The organic layer was dried over anhydrous magnesium sulfate. After concentration, silica gel column chromatography (n-hexane/ethyl acetate=10/1) gave 2-(2,2,2-Trifluoroethoxy)ethyl thioacetate (8.3 g, 87%)
