Procedure

1 g of ziprasidone free base was added to 20 mL of isopropyl alcohol, followed by 140mg of methanesulfonic acid. After a few minutes the slurry which formed thickened and lightened somewhat in color as it precipitated. The salt was harvested by filtration through a 5 μm polytetrafluoroethylene membrane.
