实验步骤: 7.7 g of 3-hydroxy-4-methoxy-benzyl alcohol, 10.35 g of potassium carbonate and 12.1 g of 1-bromo-3-methoxy-propane are stirred under reflux in 150 ml of acetone for 3 days. After evaporation of the solvent, water is added to the residue and extraction is carried out with ethyl acetate. After evaporation of the solvent the title compound is obtained from the organic extracts by means of FC (240 g of silica gel, dichloromethane/methanol=96:4): Rf (ethyl acetate/hexane=2:1)=0.31. After evaporation of the solvent, water is added to the residue and extraction After evaporation of the solvent the title compound is obtained from the organic extracts by means of FC (240 g of silica gel, dichloromethane/methanol=96:4)

实验步骤: 97 ml of trimethylbromosilane are added, with stirring at room temperature, to 113.1 g of 4-methoxy-3-(3-methoxypropyloxy)-benzyl alcohol in 1.31 litres of chloroform. After 10 minutes the solvent is evaporated off and the residue is immediately purified by means of FC (900 g of silica gel, eluant: ethyl acetate/hexane 1:3). The title compound is obtained: Rf (ethyl acetate/hexane=1:2)=0.34; m.p. 50°-51° C. After 10 minutes the solvent is evaporated off the residue is immediately purified by means of FC (900 g of silica gel, eluant: ethyl acetate/hexane 1:3)
