<p>2-(4-Isobutylphenyl)-butyric acid is prepd. by teating 4-isobutylphenylacetonitrile with diethyl carbonate to give the malonic acid deriv. of formula (II) then (II) is treated with a haloethane in an alkaline medium to give the alpha-ethyl deriv. (III) hydrolysing the ester gp. to give the corresp. acid (IV) in which the nitrile gp. is finally hydrolysed to give the desired acid.
