YieldReaction ConditionsOperation in experiment
61% With sulfuric acid; The 4-chloro-7-fluoro-6-methoxyquinazoline used as a starting material was obtained as follows: Sulphuric acid (concentrated, 120 ml) was stirred and heated to 90 C. <strong>[141483-15-0]2-Fluoro-5-trifluoromethylphenol</strong> (27 g) was added portionwise during 25 minutes. The mixture was heated to 120 C. for 10 minutes. The mixture was cooled to ambient temperature and poured onto a mixture of ice and water. The precipitate was isolated, washed with water and dried. There was thus obtained 4-fluoro-3-hydroxybenzoic acid (14.3 g, 61%).
