実験手順: A mixture of benzoxazine-2,4-dione (1.6 g, 10 mmol) and 4-chloroaniline (2.5 g, 20 mmol) in 1,4-dioxane (30 mL) was heated at reflux for 15 hours. After cooling the solid was filtered, and the filtrate was concentrated, washed with ethyl ether. The washing was concentrated further to a solid. Additional washing with cold ethyl ether (10 mL) afforded N-(4-chlorophenyl)-2-aminobenzamide as a tan solid; NMR (DMSO-d6) 10.1 (s, 1), 7.8 (d, 2), 7.6 (d, 1), 7.4 (d, 2), 7.2 (t, 1), 6.8 (d, 1), 6.6 (t, 1), 6.3 (s, 2) ppm. was heated at reflux for 15 hours After cooling the solid was filtered the filtrate was concentrated washed with ethyl ether The washing was concentrated further to a solid Additional washing with cold ethyl ether (10 mL)

実験手順: To a mixture of 2-(1-tert-butoxycarbonylpiperidin-4-yloxy)-4-(N,N-dimethyl-amino)benzoic acid (950 mg, 2.61 mmol), pyridine (0.23 mL, 2.86 mmol), DMF (1 drop) and methylene chloride (15 mL) was added oxalyl chloride (0.24 mL, 2.73 mmol) dropwise. After 15 minutes, more pyridine (0.23 mL, 2.86 mmol) was added, followed by the N-(4-chlorophenyl)-2-aminobenzamide (645 mg, 2.61 mmol). The reaction was stirred for 1 hour, diluted with methylene chloride, washed with 50% saturated aqueous sodium bicarbonate, and dried over Na2 SO4. The organic solution was concentrated, chromatographed (2000 g silica, 5% EtOAc/CH2Cl2 to 15% EtOAc/CH2Cl2), and triturated with ether to give the desired product (1.32 g, 83%). washed with 50% saturated aqueous sodium bicarbonate dried over Na2 SO4 The organic solution was concentrated chromatographed (2000 g silica, 5% EtOAc/CH2Cl2 to 15% EtOAc/CH2Cl2) triturated with ether
