Versuchsvorschrift

5.04 g of ethyl 4-(4-tert-butoxycarbonylmethylenecyclohexyl)benzoate (14.63 mmol, 1 eq.) and 15 mL of ethanol are placed in a Parr bottle. 0.31 g of 10% palladium-on-charcoal (0.29 mmol, 0.02 eq.) is added and the reaction medium is placed under 50 psi of hydrogen for 3 hours at a temperature of 25° C. The reaction medium is filtered and concentrated to give 4.31 g of ethyl 4-(4-tert-butoxycarbonylmethylcyclohexyl)benzoate.
