Procedure

To 3-amino-2-fluoro-benzoic acid (21, 1.70 g, 11 mmol) in 34 mL of dichloromethane, pyridine (2.2 mL, 27 mmol) and 4-trifluoromethyl-benzenesulfonyl chloride (22, 6.7 g, 27 mmol) were added. The reaction was stirred at room temperature overnight, then poured into water, and extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous sodium sulfate, filtered and the filtrate concentrated under vacuum to provide the desired compound 23 as a white solid, which was used in the next step without further purification.
