E and Z benzyl 3-(ethoxycarbonyl)-2-(2-methylpropyl)propenoate (25.0 g., 0.09 mol.) was dissolved in ethanol and hydrogenated at 50° C. under 37.5 psi in the presence of 5% palladium on charcoal (2.5 g). The resultant mixture was filtered through Celite and the solvent removed by evaporation in vacuo to yield 3-(ethoxycarbonyl)-2-(2-methylpropyl)propanoic acid as a mixture of isomers in the form of a thick oil.
