Reaction Steps

At ambient temp., a suspension of 2.91 g (10.4 mmol) of 2-tert-butyl-5-methyl-2-propyl-2,5-dihydrofuran and 1.06 g (1.00 mmol) of 10% palladium on activated charcoal in 60 mL of dry ether was hydrogenated for 4 h in a Parr apparatus at 2.5 bar hydrogen pressure. The catalyst was filtered off over a pad of Celite, and the solvent evaporated. The resulting residue was distilled in a Kugelrohr apparatus to provide at 75-85° C./20 mbar 2.43 g (80%) of the title compound as a colorless odoriferous liquid.
