Abstract:
The present invention relates to a process for the preparation of a chiral compound according to formula (V) wherein R1 is preferably an alkyl residue preferably having from 1 to 6 carbon atoms, in particular to a process for the preparation of a chiral compound the crystalline chiral compounds as such, and their use for the preparation of an antifungal agent, in particular posaconazole.
