Procedure

A 2 L 3 neck flask equipped with a magnetic stirrer, Frederich's condensor and an addition funnel was charged with 361 mls of bis(dimethylamino)dimethylsilane and an equal volume of tetrahydrofuran. At ambient temperature, 116 mls of anhydrous ethanol was added over one hour. Dimethylamine evolved. The mixture was transferred to a single neck flask and distilled. 264 g of dimethyl(dimethylamino)ethoxysilane, (b.p. 115°-118° C.), was recovered.
