Procedure
734 mmol (101.5 g) of potassium carbonate and 917 mmol (143.1 g) of ethyl iodide are added in succession to a solution of 367 mmol (50 g) of 2,3,6-trimethylphenol in 1500 ml of acetonitrile. The whole is heated at reflux for 48 hours. The reaction mixture is subsequently cooled and then filtered and the filtrate is concentrated. The residue obtained is dissolved in ethyl acetate and washed with water and then with 10% aqueous sodium chloride solution. After drying the organic phase and then concentrating, an oily residue is obtained which is purified by chromatography on silica gel, using a petroleum ether: ethyl acetate mixture 95:5 as eluant, to yield the expected product.
