Procedure

A mixture consisting of acetone (4750 mL) and lurasidone base (431 g) is refluxed until dissolved. Oxalic acid dihydrate (110 g) is added, and the mixture is cooled to ambient temperature, and then cooled for two hours at 10° C. The solid is filtered, and 435 g of substantially pure lurasidone oxalate is obtained after drying.
