Abstract
A factory scale process for producing crystalline atorvastatine trihydrate hemi calcium salt includes the addition of extra methyl tert-butyl ether to the reaction mixture to supersaturate the crystallization matrix. A seed slurry is made up in a make-up/delivery vessel and delivered, under pressure, to the reaction mixture. The process produces crystalline atorvastatin calcium within a consistent size range on a factory scale.
