Reaction Steps

To a stirred solution of 2,6-dimethoxyphenol (10 g) in dimethylsulfoxide (100 ml) under nitrogen was added a solution of sodium hydroxide (3.2 g) in water (20 ml). The mixture was warmed to 50° C., ethyl iodide (12.4 g) added, and stirring continued at 50° C. for 4 hours. The product was poured into 1 liter of water and the mixture extracted with diethyl ether. The extract was washed sequentially with 20% potassium hydroxide, water, and brine, and then dried over magnesium sulfate. Removal of the solvent under reduced pressure gave 1,3-dimethoxy-2-ethoxybenzene as a colorless oil (6.71 g).
