Under ice-cooling, 4.0 ml (34.5 mmol) of benzoyl chloride was added dropwise to a mixture of 4.97 g (28.8 mmol) of 3-amino-4-methyl-benzotrifluoride and 10 ml of pyridine. After stirring the mixture at room temperature for 1 hour, the solvent was removed under reduced pressure, and water was added to the residue. The precipitated solid was collected by filtration and then washed with water and a 50% aqueous methanol solution to give 8.04 g of 3-benzoylamino-4-methyl-benzotrifluoride.
