Reaction Conditions

Reaction Steps

A mixture of methyl 3,5-dimethoxy-4-hydroxybenzoate represented by Formula 87 (5 g, 23.56 mmol), 1-bromobutane (2.80 mL, 25.92 mmol), potassium carbonate (3.58 mg, 25.92 mmol) and potassium iodide (547.60 mg, 3.30 mmol) in DMF (50 mL) was agitated at 80° C. for 24 hours. After decreasing a temperature of the reaction mixture to room temperature, removing solids through filtration and adding ethyl acetate to the remaining filtrate, the filtrate was consecutively washed with water and a 5N-hydrochloric acid solution. After separating an organic layer and drying the same with magnesium sulfate, the solvent was removed under reduced pressure to form a concentrate mixture, which in turn, was subjected to separation and purification through column chromatography (ethyl acetate/hexane, 1:5) using silica gel (SiO2), resulting in an n-butylether compound represented by Formula 92 as a desired product (6.20 g, 94%). Analysis data of the product is provided as follows:
