Procedure

A solution of (+) (1S, 2R, 3S)-3-(2-carboxymethoxy-4-methoxyphenyl)-1-(3,4-methylenedioxyphenyl)-5-(prop-1-yloxy)indane-2-carboxylic acid in absolute ethanol/water (12 to 1) was titrated to pH=11-12 with 1.25 N sodium hydroxide solution then after stirring for 15 minutes, concentrated to an oil. Absolute ethanol was added and the solution reconcentrated to a solid which was triturated with hexane, and filtered. The solid was dried to constant weight to afford (+) (1S, 2R, 3S)-3-(2-Carboxymethoxy-4-methoxyphenyl)-1-(3,4-methylenedioxyphenyl)-5-(prop-1-yloxy)indane-2-carboxylic acid disodium salt.
