Versuchsvorschrift

To a solution of 2-hydroxy-3-methyl-benzoic acid (10 g, 66.7 mmol, 1.0 eq) in acetic acid (100 mL) was added bromine (10.66 g, 66.7 mmol, 1.0 eq) slowly over 5 min. The mixture was stirred at room temperature for 24 h, then water was added slowly and the mixture was stirred for a further 30 min. The precipitate was collected by filtration and was washed with water and dried to give the title compound as a white solid (13.7 g, 90%).
