Reaction Steps

To a stirred solution of 11.5 g ethyl pyruvate in 20 ml diethylether is slowly added under cooling (0° C.), a freshly prepared Grignard solution (from 23.9 g 4-chloro-iodobenzene and 3 g magnesium turnings). Some tetrahydrofurane is added to prevent the formation of viscous suspension. After stirring for 2 hours at room temperature the reaction is quenched by pouring it onto a mixture of ice and 2N sulfuric acid. Extraction of the suspension with diethyl ether followed by washing with brine, drying over sodium sulfate and evaporation leads to a residue which is purified on silicagel (hexane-ethyl acetate) to obtain 2-(4-chlorophenyl)-2-hydroxy propionic acid ethyl ester as yellowish oil.
