Sodium Iodide → 2-(Benzyloxy)-4-fluoro-1-nitrobenzene

Participants

Reaction Steps

To a solution of 5-fluoro-2-nitrophenol (8.05 g, 51.2 mmol) in acetone (100 mL) were added benzyl bromide (8.90 g, 52.0 mmol), potassium carbonate (11.0 g, 79.3 mmol) and sodium iodide (1.51 g, 10.1 mmol) at room temperature, and the mixture was heated under reflux for 2.5 hr. The reaction mixture was cooled to room temperature, the inorganic salt was filtered off, and the filtrate was concentrated. The residue was dissolved in ethyl acetate (150 mL), and the mixture was washed with water (150 mL×2) and saturated brine (100 mL), successively, and dried over anhydrous magnesium sulfate. The insoluble material was filtered off, and the filtrate was concentrated under reduced pressure to give the title compound (13.2 g) as a brown oil.
