In a 2-liter three-neck flask equipped with a stirrer, reflux condenser, dropping funnel, and thermometer were placed 30 g (1.2 gram atom) of magnesium powder, 170 g (1.00 mol) of silicon tetrachloride, and 500 ml of diethyl ether. The flask was cooled below 10° C. A mixture of 100.0 g (0.639 mol) of p-methoxybenzyl chloride and 200 ml of diethyl ether was added dropwise with stirring for the dropping funnel over 4 hours. After aging at room temperature for 1 hour, excess magnesium and magnesium chloride were removed by suction filtration. The filtrate was distilled to give 44.0 g (0.172 mol) of the desired product in a yield of 26.9%.
