How is 3-Amino-2,4,5-trifluorobenzoic acid (CAS: 119380-7) typically synthesized?

3-Amino-2,4,5-trifluorobenzoic acid can be synthesized through various methods, including the Friedel-Crafts alkylation of benzoic acid followed by nucleophilic substitution with ammonia. The synthesis often requires the use of Lewis acids as catalysts, such as aluminum chloride, and the process typically yields up to 85% purity. Specific conditions and reagents may vary depending on the desired purity and scale of production.
