Reaktionsschritte

In benzene, 2-fluoroaniline was acetylated with acetic anhydride to obtain 2-fluoroacetanilide. This 2-fluoroacetanilide was held in glacial acetic acid at 43°-52° C. and an equivalent of chlorine gas was introduced, whereby 2-fluoro-4-chloroacetanilide was obtained. This product was deacetylated with hydrochloric acid and neutralized with sodium hydroxide to recover 2-fluoro-4-chloroaniline as an oil boiling at 64°-65° C./0.25 mmHg.
