Reaction Steps
A solution of 2-(4'-aminophenyl)benzothiazole (0.5 g, 2.21 mmol) in benzene (30 ml) and acetic anhydride (0.5 g) was stirred at reflux for 4 hours and then cooled. The white precipitate was filtered off and washed with benzene. Recrystallisation from ethyl acetate gave a white powder (0.52 g, 88%), m.p. 227.2-229.1° C.
