Versuchsvorschrift

Acetyl Chloride (0.09g, 1.55 mmol) was added to a solution of 5-fluoro2-(4′-amino-3′-methylphenyl)benzothiazole (0.2 g, 0.78 mmol) in chloroform (5 ml) containing triethylamine (86 mg, 0.85 mmol). The resulting solution was stirred for 30 min, then poured into water (20 ml). The organic layer was removed, dried (Na2SO4) and evaporated. Recrystallisation from ethanol gave a white solid.
