(1R,2R,3aS,9aS)-2,3,3a,4,9,9a-hexahydro-1-((S)-3-hydroxyoctyl)-1H-cyclopenta[b]naphthalene-2,5-diol (2 g, 0.005 mol) in dry acetone (20 ml) was treated with K2CO3 (2.07 g, 0.015 mol), chloroacetonitrile (0.64 ml, 0.010 mol) and tetrabutylbromide (0.32 g, 0.001 mmol). The mixture was heated at 30° C. overnight. Then, the reaction mixture was filtered with celite pad. The filtrate 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: 82%
