Abstract: A process for the preparation of midostaurin with high purity, particularly a process for the preparation of midostaurin with a content of oxidation impurities lower than 0.1% comprising the treatment of crude midostaurin or staurosporine with strong organic or inorganic acids in a water-immiscible solvent and, optionally, also with reducing silanes is described.

Abstract: 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.

Abstract: Disclosed is a process for the synthesis of Pirfenidone (1) from 5-methyl-2(1H)-pyridinone and chlorobenzene in the presence of a catalytic system consisting of a copper salt and an organic ligand, in the presence of a base. The process exploits the high efficiency of the catalytic system consisting of copper(I) salt and an organic ligand in the presence of an inorganic base in the N-amidation reaction of chlorobenzene, a cheap reagent also usable as solvent in this case; reaction conditions at high temperatures, at atmosphere pressure or higher, produce a reaction with good yields.
