In order to be used for the synthesis of benzesterol, β-anisyl-α-ethylvaleric acid was prepared as follows: Condensation of anisaldehyde and ethyl malonate yielded ethyl anisalmalonate to which was applied ethylmagnesium iodide to effect 1, 4-addition to obtain ethyl α-anisylpropylmalonate, followed by the application of sodium and ethyl iodide to yield ethyl α-anisylpropylethylmalonate. The hydrolysis and decarboxylation of the latter yielded the objective compound.
