YieldReaction ConditionsOperation in experiment
64% With sodium hydroxide; n-butyllithium In tetrahydrofuran; hexane; water; ethyl acetate PREPARATION 57
2-Fluoro-5-(trifluoromethyl)benzoic acid
To a solution of 99 g (0.6 mole) of fluoro-(4-trifluoromethyl)benzene in 750 ml of tetrahydrofuran a -60° C. and under nitrogen was added dropwise 256 ml of 2.5 molar butyllithium in hexane (0.64 mole) over a 1 hr period.
The reaction mixture was stirred at -60° C. to -70° C. for 4 hr and poured onto a large excess of dry ice.
After 15 minutes the excess dry ice was evaporated with some external heat and the solvent removed by rotary evaporation.
The residue was taken up in 500 ml of water and 30 ml of 1N sodium hydroxide and washed with 2*300 ml of ethyl acetate.
The aqueous was acidified with concentrated hydrochloric acid and extracted with 2*300 ml of ethyl acetate.
The combined organic extracts were washed with 500 ml of water followed by 300 ml of brine, dried over sodium sulfate and concentrated by rotary evaporation.
The crude residue was crystallized from hexane to give 80 g (64percent yield based on aliquot taken) of white analytically pure crystals, m.p. 100°-100.5° C.
Analysis:
Calculated for C8 H4 O2 F4: C, 46.17; H, 1.94. Found: C, 46.16; H, 1.89.
