Reaction Steps

A mixture of 8-chloro-1H-benzo[d][1,3]oxazine-2,4-dione (0.80 g, 4.05 mmol) and 4-bromoaniline (0.70 g, 4.05 mmol) with anhydrous DMF (1 mL) was heated at 130° C. for 2 hours. Water (50 mL) was added, and the product was extracted with ethyl acetate (200 mL). The organic phase was separated, washed with water (100 mL), brine (100 mL) and dried over anhydrous Na2SO4. The solvent was evaporated in vacuo, and the crude material was washed with ether, to give 2-amino-N-(4-bromophenyl)-3-chlorobenzamide as an off-white solid. Yield 1.17 g (89%).
