Disclosed is a process for the synthesis of iloperidone starting from 4-hydroxy-3-methoxy acetophenone (acetovanillone), 1-chloro-3-bromo propane and 6-fluoro-3-(4-piperidinyl)-1,2-benzisoxazole hydrochloride, using a one-pot method.
Said process is performed without any intermediate isolation, and is particularly advantageous from the environmental standpoint and in terms of yields, productivity and the purity of the product obtained, both in the reaction mixture and in the crystal isolated.
