Procedure

1-Allyl-2,2,7,7-tetramethylcycloheptan-1-ol (15.00 g, 0.09 moles), 5 wt % Pd/C (1.00g, 0.33 wt % Pd) and n-hexane (20 ml) were added to an autoclave. The air in the autoclave was replaced by nitrogen, followed by applying to a H2 pressure of 50 atm and heating the autoclave to 50° C. under stirring. The reaction was determined as completed at the time when the gas absorption was stopped. It required about 2 hours in this case. The autoclave was cooled down to room temperature and returned to a normal pressure, after which the content was withdrawn. The content was concentrated and subjected to fractionation to obtain 11.90 g (yield 77.6%) of the captioned compound. This compound was a colorless transparent liquid having a woody, earthy and patchuli oil-like odor.
