실험 절차

To a stirred solution of 4-fluoroaniline (2.4 mL, 25 mmol) and pyridine (6.1 mL, 75 mmol) in dichloromethane (30 mL) was added 2-nitrobenzoyl chloride (3.6 mL, 28 mmol). After 12 h, the mixture was diluted with dichloromethane and washed with 1 N aqueous citric acid, saturated aqueous sodium chloride solution, saturated aqueous sodium bicarbonate solution, dried (magnesium sulfate), filtered, and concentrated in vacuo. The resulting solid was suspended in diethyl ether, sonicated, filtered and dried in vacuo to give 5.1 g (79%) of the title compound as a tan solid.
