Reaction Steps
To a stirred solution containing 17.3 g (0.075 mole) of 3,5-ditrifluoromethylphenol, 5 g (0.075 mole) of 85% potassium hydroxide, 150 ml of dimethylformamide and 7 ml of water, 14.6 g (0.08 mole) of ethyl 2-bromopropionate was added in one portion. The stirred reaction mixture was heated at 80°-90° C. for 24 hours. After cooling to 25° C., 500 ml of water and 500 ml of ethyl ether were added and stirring was continued for 15 minutes. The separated ether layer was washed with water until neutral to litmus and dried over sodium sulfate. The ether was removed in vacuo at maximum temperature of 50°C. at 1-2 mm of Hg. The resulting product was obtained as an amber liquid, ND25 =1.4184 in 97% yield.
