A method for synthesizing (phenylalkyloxy)phenyl-oxobutanoic acid compounds is described. The corresponding (phenylalkyloxy)acylphenyl compound is halogenated, giving the alpha haloketone. The halide is displaced by the anion of a di-alkyl malonate to give a substituted malonic ester. Hydrolysis of the ester and decarboxylation of the diacid gives the desired product.
