Reaction Steps

To a stirred solution of 5-hydroxy-2-benzothiazolesulfonamide (7.0 g., 0.03 mole), triethylamine (4.2 ml., 0.03 mole) and 4-dimethylaminopyridine (200 mg., catalyst) in dimethylformamide (25 ml.) is added benzoyl chloride (1.4 g., 0.01 mole). The reaction mixture is stirred at 25° C. for 11/2 hours and then poured into ice water (150 ml.) containing excess hydrochloric acid to give 2-sulfamoyl-5-benzothiazolyl benzoate.
