1. Using o-fluoroaniline as raw material, it reacts with chloral hydrate and hydroxylamine hydrochloride to synthesize 2-amino derivatives, then converts to 7-fluoroisatin in concentrated sulfuric acid, and finally oxidizes with hydrogen peroxide under alkaline conditions to obtain 2-amino- 3-fluorobenzoic acid. 2. The synthesis of 2-amino-3-fluorobenzoic acid is based on 2-bromo-3-fluorobenzoic acid |
