Procedure

To a solution of ethyl (RS)-1-(2-methoxyphenyl)-3-(3,4-methylenedioxyphenyl)indene-2-carboxylate (90 mg, 0.22 mmol) in EtOH (10 ml) was added 10% palladium on activated carbon (90 mg). The resulting suspension was shaken on a Parr hydrogenator at 60 psi H2 overnight, then was filtered through a pad of Celite. The filtrate was concentrated under reduced pressure to afford the title compound (90 mg, 100%), which was used without further purification.
