Methyl iodide → 2-Bromo-4-methoxy-1-(trifluoromethoxy)benzene

Participants

Reaction Steps

To a stirred suspension of 3-Bromo-4-trifluoromethoxy-phenol (20.0 g, 82.6 mol) and potassium carbonate (46.3 g, 330.4 mmol) in acetone (600 ml) was added drop-wise iodomethane (46.9 g, 330.4 mmol) under an atmosphere of nitrogen. The resulting mixture was stirred at reflux for 2 hours. The reaction mixture was cooled to room temperature then filtered and the filtrate was evaporated in vacuo to afford the title compound as a colourless oil (19.8 g, 93%).
