Reaction Steps

Synthesized according to general procedure 71. A solution of 2,2,2-trifluoro-N-(2-methyl-4-(N-thiazol-2-ylsulfamoyl)phenyl)acetamide (1 g, 2.74 mmol), NaOH (1.09 g, 27.4 mmol), and H2O (5 mL) was stirred at RT for 1 h, then cooled to 0° C. 1 N hydrochloric acid (27.4 mL, 27.4 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-methyl-N-(thiazol-2-yl)benzenesulfonamide (232 mg, 31%).
