Reaction Steps

A stirred suspension of 5-methoxy-2-benzothiazolesulfonamide (11.8 g, 0.048 mole) and aluminum chloride (28 g, 0.21 mole) in heptane (500 ml) is heated at reflux for 21/2 hours then cooled. The aluminum chloride complex is decomposed by the addition of ice water (400 ml) to give 6.5 g of 5-hydroxy-2-benzothiazolesulfonamide which melts at 224° C. after reprecipitation from dilute sodium hydroxide with dilute hydrochloric acid.
