Versuchsvorschrift
1-(4-Benzyloxyphenyl)-heptane-1,3-dione (4 g; see step (a) above) was dissolved in toluene (20 ml) and Pd/C (3%; 80 mg) was added. The mixture was stirred at room temperature until hydrogen uptake ceased. After filtration of the catalyst, the solvent was evaporated leaving 2.84 g, 100%, 1-(4-hydroxyphenyl)-heptane-1,3-dione.
