Versuchsvorschrift
A solution of 5.72 g of the 2-(4-chlorophenyl)-2-hydroxy propionic acid ethyl ester in 170 ml tetrahydrofurane is hydroysed at 0° C. with a solution of 30.5 ml 1N lithiumhydroxide in 19 ml water. When the reaction is complete, the reaction mixture is diluted with water, washed with diethyl ether, acidified with 1N HCl and extracted with ethyl acetate. The extracts are washed with brine, dried over sodium sulfate and evaporated to give 2-(4-chlorophenyl)-2-hydroxy propionic acid.
