Procedure

A Parr hydrogenation bottle was charged with 10% palladium on carbon (0.1 equivalent) and ethyl acetate. A solution of 2-propylpent 4 enal, prepared as in Example 5, in ethyl acetate was added. The mixture was hydrogenated at 300N/m2 hydrogen in a Parr hydrogenation apparatus at room temperature until hydrogen uptake ceased. The catalyst was removed by filtration through celite. The filtrate was concentrated to give the desired product as a colorless oil. The product was used without further purification.
