Reaktionsschritte
12 g of 3-amino-2-chloro-5-fluoro-4-methylbenzoic acid are initially introduced into 60 ml of MeOH. HCl gas is passed in for 20 minutes and is then boiled under reflux for 5 hours. Thereafter, the mixture is poured into water and rendered alkaline with sodium carbonate and the product is isolated. Yield: 8 g, melting point: 51°-52°.
