Reaktionsschritte
A mixture of 2-(4'-aminophenyl)benzothiazole (0.3 g, 1.32 mmol) and benzoyl chloride (0.3 ml) in pyridine (8 ml) was stirred at reflux for 2 hours, then cooled and poured into water (100 ml). The precipitate formed was filtered off, washed with water and dissolved in hot dichloromethane (12 ml). The resulting solution was cooled in an ice-bath and the solid was filtered off. The filtrate was evaporated and the residue was recrystallised from dichloromethane-methanol to give a white powder (0.36 g, 82.2%), m.p. 227.1-228.5° C.
