    Abstract: Disclosed is a process for the industrial synthesis of Lurasidone from (1R,2R)-cyclohexane-1,2-diyldimethanol (1), 3-(piperazin-1- yl)benzo[d]isothiazole (3) and (3aR,4R,7R,7aS)-3a,4,7,7a-tetrahydro-4,7- methanoisobenzofuran-1,3-dione (6).). Said process is optimised to obtain Lurasidone with high yields and high purities by preparing highly pure synthesis intermediates, using critical raw materials and reagents in amounts close to the stoichiometric amounts, increasing productivity and reducing the costs and environmental impact of the process.
