PROCESS FOR THE PREPARATION OF CHIRAL TRIAZOLONES

摘要

A process for the preparation of a chiral compound, in particular posaconazole, wherein the process comprises mixing and reacting the compounds of formula (I) Y3-NH2; of formula (Ila) 0=C=N-Y0 and/or of formula (lIb) and of formula (III) in a solvent in any order to obtain a reaction mixture containing a chiral compound of formula (IV) and/or formula (V).
