Versuchsvorschrift

A solution of ethyl 2-(4,4-dimethyl-2-cyclohexene-1-ylidene)acetate (Preparation 13, 4.0 g, 21 mmol) in methanol (40 ml) was treated with 5% palladium on carbon, and the suspension was placed under an atmosphere of hydrogen (60 p.s.i.) at room temperature for 48 h. The mixture was filtered through a short pad of silica (40 g) and the filtrate was concentrated in vacuo to afford the title compound as a colourless oil (3.7 g, 91%).
