To a suspension of sodium hydride (60 % oil dispersion; 4.0 g) in N,N-dimethylformamide (100 ml), 2-phenylphenol (17.0 g) was added at a temperature of 0 to 5° C., and the resultant mixture was stirred at room temperature for 1 hour. 2-Fluoroethyl methanesulfonate (14.2 g) was added thereto. The resulting mixture was heated to 90° C., followed by stirring for 5 minutes. The reaction mixture was poured onto ice-water and extracted with ethyl acetate. The extract was washed with aqueous potassium carbonate solution, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluting solvent, toluene) to give 1-(2-fluoroethoxy)-2-phenylbenzene (Compound No. 20) (16.4 g). nD24.8 1.5796.
