Versuchsvorschrift

A 5.2 g portion of 60% sodium hydride oil dispersion was suspended in 50 ml of DMF, and 6.73 ml of benzyl alcohol was added thereto under ice-cooling. After warming up to room temperature, 12.3 g of 4-fluoro-2-trifluoromethylbenzoic acid was added thereto and stirred at room temperature for 6 hours. A 1 M hydrochloric acid aqueous solution was added to the reaction mixture, and the thus precipitated crystals were collected by filtration to obtain 16.39 g of 4-(benzyloxy)-2-(trifluoromethyl)benzoic acid.
