Zusammenfassung:The present invention provides an industrial method production of amorphous posaconazole. The present invention also relates to a method for production of the posaconazole via and novel crystalline forms of posaconazole intermediate. More particularly the present invention relates to novel crystalline forms of posaconazole intermediate and methods for production of novel crystalline forms of posaconazole intermediate represented by the following structural formula III Which is key intermediate in the production of posaconazole. The present invention also provides for the one pot process for the preparation of amorphous posaconazole using novel crystalline forms of benzyl posaconazole.
