Procedure

3.15 g (0.01 mole) of 3-(2-n-propyl-3-hydroxy-4-acetylphenoxy)1-bromopropane was dissolved in 50 ml of dry acetone. To this solution was added 2.75 g (0.02 mole) of anhydrous potassium carbonate and 3 g (0.02 mole) of methyl iodide. After refluxing for four days under an argon atmosphere, the reaction mixture was filtered and the filtrate concentrated on the rotary evaporator. The residue was chromatographed on silica gel eluting with 2% ethyl acetate/toluene to give 3.1 g (94%) of the title compound as an oil.
