Procedure
A mixture of 2-(cyclopropanecarbonyl-amino)-5-hydroxy-benzoic acid (7.0 g, 32 mmol) and 2-(trifluoromethyl)-benzyl bromide (9.09 g, 38 mmol) in 0.5 M KOH (158 mL, 79 mmol) and acetone (200 mL) was heated to reflux. After 4 hours, acetone was evaporated and the resulting mixture was diluted with more water and washed with CH2Cl2. The water phase was acidified with 1 M HCl and the resulting solid was collected by filtration. Recrystallisation in methanol gave the product as an off-white powder (6.0 g, yield 50%).
