実験手順

(3-Fluoro-5-trifluoromethyl-phenyl)-hydroxy-acetic acid methyl ester 91 (0.1 mol) was dissolved in dimethylformamide (100 mL) and sodium hydride (0.1 mol) was added. When hydrogen evolution stopped, a solution of 2-fluoro-4-chloro-1-trifluoromethyl-benzene 92 (0.1 mol) in dimethylformamide (25 mL) was added. The progress of the reaction was monitored by TLC. When the reaction was complete, water and ethyl acetate were added. The organic phase was dried and concentrated, and the residue was chromatographed to afford (3-fluoro-5-trifluoromethyl-phenyl)-(5-chloro-2-trifluoromethyl-phenoxy)-acetic acid methyl ester 93. Basic hydrolysis of this compound, as described in Example 1, then afforded the title compound 94.
