A process for obtaining a substantially pure enantiomer of an aryl-substituted aliphatic carboxylic acid is described. The process combines an aryl substituted aliphatic carboxylic acid, a base and water in an inert solvent to make a hydrated salt of the said acid. The process leads to enhanced yield of an enantiomerically enriched hydrated salt of the carboxylic acid.
