実験手順

Benzylamine (20 mL, 182 mmol) and Et3N (15.2 mL, 109 mmol) are added to a solution of bis-(bromomethyl) dimethylsilane 2 (10 g, 36.5 mmol) in chloroform (100 mL). The mixture is then refluxed for 16 h. 5% sodiumhydroxide solution (150 mL) is then added and the aqueous layer is extracted with dichloromethane (DCM, 2×100 mL). It is then washed with brine (200 mL), dried and concentrated. The product is purified by column chromatography on silica gel using hexane-EtOAc mixtures to obtain the product 3 as a light yellow liquid (4.3 g) in 54% yield.
