実験手順

Under a nitrogen atmosphere, dimethoxydimethylsilane (31) (1.0 ml, 7.0 mmol) was added to a reaction container, cooled down to 0° C., diethyl ether solution of 0.72M 3-(triallylsilyl)propylmagnesium bromide (24) (19.44 mL, 14 mmol) was added dropwise. After the dropwise adding, stirring was continued at room temperature for 5 hours. To the reaction mixture, water was added to stop the reaction, then 10% hydrochloric acid was added until the salt was completely dissolved. The obtained organic layer was separated and the obtained water layer was extracted with diethyl ether. The collected organic layer was washed each with saturated sodium bicarbonate aqueous solution and saturated saline solution in this order, dried over anhydrous magnesium sulfate, then filtered, concentrated under reduced pressure, obtaining {3-(triallylsilyl)propyl}(methoxy)dimethylsilane (32) represented by the following chemical reaction equation (yield: 1.5 g, yield (%): 72%).
