実験手順

2-isopropylaniline (27 g, 200 mmol), 2-fluoronitrobenzene (14 g, 100 mmol), and potassium fluoride (8.6 g, 150 mmol) were mixed in a one-neck flask. The mixture was heated up to 180° C. under nitrogen for 48 hours. After cooled to room temperature, water (200 mL) was added. The mixture was then extracted with dichloromethane (200 mL) for three times. The solvent was evaporated and the residue was purified by column chromatography using 20% of dichloromethane in hexanes. 22.5 g of desired product was obtained.
