Reaction Steps

(1R,2R,3aS,9aS)-2,3,3a,4,9,9a-hexahydro-2-hydroxy-1-((S,E)-3-hydroxyoct-1-enyl)-1H-cyclopenta[b]naphthalen-5-yl benzoate (0.35 g, 0.8 mmol) in dry methanol (2.5 ml) was treated with 5% Pd/C (0.05 g, 20% wt) and stirred under hydrogen for 5 hours at room temperature. Then, the reaction mixture was filtered with celite pad. The solvent was evaporated off under vacuum. The crude product was purified by chromatography on silica gel using a mixture of hexane and ethyl acetate as a gradient eluent. Yield: 87%.
