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.

Claim (Index 3):
The process of  claim 1 , wherein said arylation is carried out at a pressure higher than atmospheric pressure at a temperature ranging between 120 and 190\u00b0 C.
