PROCEDURE

实验过程

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 liters 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.
