実験手順
To a mixture of 2,3,4,5,6-pentafluorobenzoic acid (1 g) and 2,2,3,3,4,4,5,5-octafluoropentanol (1.18 g) in N,N-dimethylformamide (5 ml) was added 62% sodium hydride (0.39 g) at room temperature. The mixture was stirred at the same temperature for 1 hour, and thereto was added a mixture of water and ethyl acetate. The separated organic layer was washed with water and brine, dried over magnesium sulfate, and evaporated in vacuo. The residue was purified by chromatography on silica gel to give 4-(2,2,3,3,4,4,5,5-octafluoropentyloxy)-2,3,5,6-tetrafluorobenzoic acid (923.0 mg).
