Process for the synthesis of pirfenidone |
| abstract |
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. |
