A suspension of trans-(E)-3-[4-(1,1-dimethylethyl)cyclohexyl]-2-propenoic acid ethyl ester (3.6 g, 15.1 mmol) in abs. EtOH (388 mL) and 5% Pd/C (1.4 g) was hydrogenated at 1 atm for 2 h. The catalyst was filtered over Celite and the filtrate and washings were concentrated to dryness to give trans-4-(1,1-dimethylethyl)cyclohexanepropanoic acid ethyl ester (3.58 g, 14.9 mmol) in 99% yield.
