Benzyl 6-hydroxy-6-(4,4-dimethyl-2,6-dioxocyclo-hexylidene)-hexanoate (1.50 g, 4.19 mmol) was hydrogenated over Pd/C (10%) (150 mg) in MeOH (20 ml) at room temperature for 10 hours. The catalyst was filtered off, and the filtrate was evaporated, yielding 6-hydroxy-6-(4,4-dimethyl-2,6-dioxocyclohexylidene)-hexanoic acid (1.10 g, 98%);
