Participants

Reaction Steps

0.5 g of 5% palladium on charcoal as a catalyst was added to 10.5 g of ethyl 6-isopropyl-2-methyl-3-cyclohexene-1-carboxylate (mixture of isomers obtained according to Example 1) dissolved in 100 ml of ethanol, after which the mixture was hydrogenated at 20° C. for 1 hour under a hydrogen pressure of 100 kPa. The catalyst was then filtered off, the filtrate evaporated down and the evaporation residue distilled. 9.4 g of the desired compound were obtained as a mixture of the cis-trans and the trans-trans isomer. b.p.: 96°-97° C./1 kPa; NMR (of the mixture): 0.7-1.0 (9H); 1.24 (3H, t); 1.0-2.5 (10H); 3.9-4.2 (2H).
