Procedure

Allyl (1S, 2R, 3S)-3-(2-carbo-tert-butoxymethoxy-4-methoxyphenyl)-1-(3,4-methylenedioxyphenyl)-5-(prop-1-yloxy)indane-2-carboxylate (765 mg, 1.24 mmol) was dissolved in TFA (5 ml) containing a few drops of anisole. The reaction mixture was stirred at RT for 20 min. The solvent was eliminated, the residue was diluted with ethyl acetate, washed with water, brine and dried (MgSO4 anhyd.), filtered and evaporated. The product was purified by column chromatography to provide the title compound (575 mg, 83%) as a colorless oil.
