Hydrochloric Acid → 4-Anilino-3-nitrobenzoic acid

참여 물질

반응 단계

4-Fluoro-3-nitrobenzoic acid (21.6 mmol) and an aniline (43.2 mmol) in 15 mL of ethanol were stirred at reflux under argon for 5 h resulting in the formation of an orange precipitate. After 12 h the heterogeneous reaction mixture was poured into 50 mL of 1N HCl(aq) and diluted with 100 mL of water. The solution was stirred for 20 min then the precipitate filtered to yield the 4-anilino-3-nitrobenzoic Acid: e.g. 4-{[3-(benzyloxy)phenyl]amino}-3-nitrobenzoic acid.
