Procedure

A mixture of 100 millimoles diethyl 2-(2-fluoro-4-biphenylyl)-methylmalonate VI, 110 millimoles sodium chloride, 200 millimoles water and 50 milliliters dimethyl sulfoxide is heated under nitrogen at about 130° to 180° C. for about 6 hours. On cooling the mixture is diluted with 100 milliliters water and 100 milliliters ethyl acetate. The layers are separated and the organic layer is washed two times with 25 milliliters of water. After drying over disodium sulfate the organic layer is concentrated in vacuo to give the desired ethyl 2-(2-fluoro-4-biphenylyl)propionate.
