A solution of (2SR,9aSR)-2-allyl-9a-butyl-7-methoxymethoxy-4-methyl-1,2,9,9a-tetrahydro-3H-fluoren-3-one (5 mg, 0.015 mmol) in THF (0.5 mL) was treated with 6N HCl (0.5 mL) and the resulting solution was heated at 50° C. overnight. The mixture was diluted with EtOAc (30 mL), washed with 5% NaHCO3 and brine, dried over MgSO4, filtered, and evaporated under vacuum to a yellow oil. The crude product was purified by PLC on a 0.025×20×20 cm silica gel GF plate using 2:1 hexanes-EtOAc as developing solvent. The UV visible band at Rf 0.43-0.57 afforded (2SR,9aSR)-2-allyl-9a-butyl-7-hydroxy-4-methyl-1,2,9,9a-tetrahydro-3H-fluoren-3-one as a gum.
