実験手順
A solution of 1H-benzo[d][1,3]oxazine-2,4-dione (2.0 g, 12.2 mmol) and 4-isopropylaniline (1.92 mL, 13.5 mmol) in anhydrous DMF (10 mL) was stirred at 115° C. for 6 hours under nitrogen. DMF was removed and the residue was mixed with water (100 mL) and dichloromethane (150 mL). The organic phase was separated and washed with brine (50 mL). The solvent was removed and the residue was washed with ether (50 mL) to give 2-amino-N-(4-isopropyl-phenyl)-benzamide as a solid. Yield: 0.80 g (25.8%).
