Abstract (en)
[origin: WO2005070937A1] Heating a solid, preferably crystalline, olanzapine acetate can produce olanzapine Form I in high purity, free of other olanzapine forms and in good yields. The olanzapine acetate can also be used to purify raw or technical grade olanzapine and to serve as an intermediary to other forms of olanzapine base.
