Reaction Steps

To a solution of 1H-benzo[d][1,3]oxazine-2,4-dione (1.63 g, 10.0 mmol) in anhydrous DMF (20 mL) was added 4-trifluoromethyl-aniline (1.61 g, 10.0 mmol) and the reaction mixture was stirred at 115° C. for 16 hours. It was then cooled to room temperature, diluted with ethyl acetate (150 mL), and the organic phase was washed with water (100 mL), 10% aq. NaOH solution (100 mL), water (150 mL), brine (150 mL), and dried over anhydrous Na2SO4. Solvent was evaporated and the crude compound was purified by the Simpliflash system (20% ethyl acetate in hexanes as eluent) to give 2-amino-N-(4-trifluoromethyl-phenyl)-benzamide as an off-white solid. Yield: 0.2 g (7%).
