Reaktionsschritte
4.3 Grams of 2-fluoro-4-hydroxybenzoic acid and 8.4 g of acetic anhydride were placed in a two-necked flask and mixed. While the mixture was cooled with water, 5 drops of sulfuric acid was added. After the heat generation ended, the mixture was heated at 80° C. for 30 minutes. Then, the reaction mixture was poured into cold water, and precipitated crystal was recovered by filtration. The crystal was dried under vacuum and used in a subsequent step. The yield of the crystal was 4.7 g.
