Procedure

Synthesized according to general procedure 71. A solution of 2,2,2-trifluoro-N-(2-fluoro-4-(N-thiazol-2-ylsulfamoyl)phenyl)acetamide (2.0 g, 5.42 mmol), NaOH (2.17 g, 54.2 mmol), and H2O (9.7 mL) was stirred at RT for 1 h, then cooled to 0° C. 1 N hydrochloric acid (54.2 mL, 54.2 mmol) was added, and the reaction was stirred at 0° C. for 20 min. The formed precipitate was filtered off and dried under vacuum to give 4-amino-3-fluoro-N-(thiazol-2-yl)benzenesulfonamide (1.03 g, 70%). LC/MS (10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA)), m/z: M+1 obs=274.1; tR=0.51 min
