E and Z benzyl 3-(ethoxycarbonyl)-2-(2-methylpropyl)butenoate (5.0 g.) was hydrogenated at 120 psi at 60° C. in methanol (50 mls.) in the presence of 10% palladium on charcoal (0.25 g.) for 48 hours. The resultant mixture was filtered through Celite and the solvent removed by evaporation in vacuo to yield 3-(ethoxycarbonyl)-2-(2-methylpropyl)butanoic acid as a mixture of isomers in the form of a thick oil.
