Methyl iodide → 3,5-Bis(trifluoromethyl)anisole

Participants

Reaction Steps

A mixture of 3,5-bis(trifluoromethyl)phenol (47, 1.0 g, 4.35 mmol), methyl iodide (0.7 mL, 10.8 mmol) and K2CO3 (3 g, 21.75 mmol) in acetone (10 mL) was heated to reflux while stirring overnight. Solid residue was filtered off and the filtrate was concentrated on warm water bath at atmospheric pressure (Caution: product was volatile) to afford 1-methoxy-3,5-bis(trifluoromethyl)benzene (48, 0.6 g, 56%) as clear oil: 1H NMR (300 MHz, CDCl3) δ 7.46 (s, 1H), 7.30 (s, 1H), 3.90 (s, 1H).
