Beschreibung
Zusammenfassung:	The invention relates to a method for the production of crystalline forms of optical enantiomers of modafinil, comprising the following steps:i) one of the optical enantiomers of modafinil is dissolved in a solvent other than ethanol; ii) the enantiomer of modafinil is crystallized; iii) the crystalline form of the enantiomer of modafinil thus obtained is recovered. The invention also relates to a method for the production of optical enantiomers of modafinil.
