Methyl iodide → 3-Fluoro-4-nitroanisole

Participants

Reaction Steps

To a solution of 3-fluoro-4-nitro-phenol (25.3 g, 0.16 mol) in acetone (160 ml), potassium carbonate (41.7 g, 0.30 mol) and methyl iodide (20.0 ml, 0.32 mol) are added at ambient temperature. The reaction mixture is stirred at 40 C.° for 3 h. After cooling down to room temperature, dichloromethane is added to the reaction mixture, which is filtrated and evaporated. Dichloromethane is added to the residue and the organic phase is washed with H2O and brine, dried over sodium sulfate and evaporated down to give 2-fluoro-4-methoxy-1-nitro-benzene in 98% yield.
