What is the reagent catalyst and solvent from aniline to acetanilide?

To convert aniline to acetanilide, the reagent used is acetic anhydride or acetyl chloride. The reaction typically requires a catalyst such as a base, like pyridine, to facilitate the acetylation. The solvent can be a non-polar organic solvent like dichloromethane or toluene, although the reaction can also proceed without a solvent.
