Versuchsvorschrift
To sodium thiosulfite (2.6 g, 20.7 mmol) and sodium bicarbonate (1.74 g, 20.7 mmol) in water (20 mL) at 75° C. add 3-bromo-5-chlorosulfonyl-4-fluorobenzoic acid (6.25 g, 19.7 mmol) in portions over 5 min. After 1 h, cool to room temperature and add chloroacetic acid (5.29 g, 56 mmol) and NaOH (1.18 g, 29.5 mmol) and reflux 16 h. Cool to room temperature and collect the title compound as a solid
