HCID 18548624Benzoic acid, 2-amino-5-fluoro-3-nitro- (9CI)Yield 92%

Procedure

2-Acetamido-5-fluoro-3-nitrobenzoic acid (200 mg, 0.83 mmol) was added to 3N hydrochloric acid (4.0 mL) and the solution allowed to reflux for 7 hours whereby the solution contained a bright yellow precipitate. The reaction was cooled to room temperature and the precipitate collected and dried to produce 2-amino-5-fluoro-3-nitrobenzoic acid (152 mg, 92%) as a yellow solid.
