Method for the production of crystalline forms and crystalline forms of optical enantiomers of modafinil

Abstract : The invention relates to a process for the preparation of crystalline forms of the optical enantiomers of modafinil, comprising stages comprising: i) dissolving one of the optical enantiomers of modafinil in a solvent other than ethanol, ii) crystallising the modafinil enantiomer, iii) recovering the crystalline form of the modafinil enantiomer so obtained. The invention also relates to a process for the preparation of the optical enantiomers of modafinil.
