Procedure

Methyl (1RS,2SR,3RS)-3-[2-(3-Carbomethoxyphenyl)-4-methoxyphenyl]-1-(3,4-methylenedioxyphenyl)-5-(prop-1-yloxy)indane-2-carboxylate (0.08 g, crude) was dissolved in propan-2-ol (1 ml) and aqueous sodium hydroxide (1M, 1 ml, 1 mmol) added. The mixture was refluxed for 12 hr. then cooled, diluted with water, acidified with 3M-aqueous hydrochloric acid and extracted with ethyl acetate (3×). The combined organic extract was purified by column chromatography on silical-gel (eluant: 30% EtOAc/hexane/5%AcOH) to give the title compound as a colorless solid (20 mg)
