Procedure: 4-Fluorobenzenethiol (0.50 ml, 4.69 mmol) and 2-bromoethanol (0.345 ml, 4.87 mmol) was dissolved in tetrahydrofuran (12 ml). The solution was added with 1N aqueous solution of sodium hydroxide (4.8 ml,4.8 mmol) and heated at 80° C. for 80 minutes with stirring. The reaction mixture was diluted with a mixed solvent of ethyl acetate-hexane, and washed with diluted aqueous solution of sodium hydroxide, water, and then with saturated brine, and dried over magnesium sulfate. Insoluble solids were removed by filtration and the filtrate was concentrated under reduced pressure to obtain 2-(4-fluorophenylthio)ethanol as crude product. By using the resulting product, 2-(4-fluorophenylthio)ethanol ethanesulfonate was obtained as crude product by similar procedures to those of Example 26a. By using the resulting product, the title compound was obtained as colorless solid by similar procedures to those of Example 26b (yield: 64%). washed with diluted aqueous solution of sodium hydroxide, water with saturated brine, and dried over magnesium sulfate Insoluble solids were removed by filtration the filtrate was concentrated under reduced pressure
