Reaction Conditions

Reaction Steps

A stirred charge containing 0.05 mole of ethyl-2-[3,5-bis-(trifluoromethyl)phenoxy]propionate, 150 ml of ethyl alcohol, 8 g (0.1 mole) of 50% aqueous solution of sodium hydroxide and 25 ml of water was heated at reflux for 5 hours and at 25°-30° C. for 18 hours. After cooling to 5° C. 800 ml of water containing 15 g (0.15 mole) of concentrated hydrochloric acid was added slowly. After stirring at 0°-10° C. for one hour, the resulting solid was collected by filtration, washed with cold water and air-dried at 25°-30° C. A product with a melting point of 51°-53° C. was obtained with a yield of 97%.
