Reaction Steps
To a solution of the benzoic acid (2) (180 mg, 0.55 mmol) in tetrahydrofuran (6 mL) was added 1,1′-carbonyldiimidazole (98 mg, 0.60 mmol). After a period of 2 h, 4-fluoroaniline (61 mg, 0.55 mmol) in tetrahydrofuran (1.5 mL) was added and the mixture was stirred at 75° C. overnight. The tetrahydrofuran was removed in vacuo and the residue was redissolved in ethyl acetate, washed with 10% aqueous hydrochloric acid, saturated aqueous sodium hydrogen carbonate, dried (MgSO4) and concentrated to give an oily residue which was subjected to silica-gel column chromatography [eluent: Ethyl acetate:Hexane, 20:80, ν/ν->60:40, ν/ν] to give the title quinazolinone (3) (0.11 g, 50%) as a white solid:
