4-Methyl-3-nitroaniline (5 g, 32.9 mmol) was stirred in a solvent of dichloromethane (150 mL). The reaction solution was added with DIPEA (11.48 mL, 65.7 mmol) and 3-(trifluoromethyl)benzoylchloride (4.86 mL, 32.9 mmol), and stirred for about an hour at room temperature. The reaction mixture was washed with 1M aqueous HCl solution, an aqueous sodium bicarbonate and saline. The organic layer was dried over anhydrous sodium sulfate, filtered, and concentrated under reduced pressure to obtain the title compound (10.6 g, 99%).
