0.150 g of ethyl trans-4-[4-((E)-2-tert-butoxycarbonylvinyl)cyclohexyl]benzoate (0.42 mmol, 1 eq.) is dissolved in 15 mL of ethanol in a Parr bottle. 0.044 g of 10% palladium-on-charcoal (0.04 mmol, 0.1 eq.) is added and the medium is subjected to 50 psi of hydrogen for 5 hours. The medium is filtered through Whatman paper, washed with ethanol and evaporated to give 0.19 g of ethyl trans-4-[4-(2-tert-butoxycarbonylethyl)cyclohexyl]benzoate.
