Versuchsvorschrift

A stirred mixture of 4-methoxy-2-trifluoromethylbenzoic acid (0.50 g, 2.27 mmol) and thionyl chloride (9 ml) was heated under reflux for 4 h. After cooling to room temperature, the excess reagent was removed under reduced pressure to give crude acid chloride. The amide was prepared as described in the Amide Coupling section using the crude 4-methoxy-5-trifluoromethylbenzoyl chloride and 2-(4-aminophenyl)-6-methoxybenzo thiazole (0.58 g, 2.27 mmol) in dry pyridine (15 ml) to give the title compound (0.478 g, 46%) as pale yellow needles after work-up and recrystallisation from acetic acid.
