Procedure

The rosuvastatin potassium salt obtained is further treated with mixture of toluene and ethyl acetate followed by treatment with suitable calcium source like calcium chloride, calcium acetate, calcium hydroxide and the like. In particular, calcium acetate is used to obtain rosuvastatin calcium salt. The isolated rosuvastatin calcium is in amorphous form.
