Versuchsvorschrift

Benzylamine (17.56 g, 0.16 mol) and K2CO3 (3.4 g, 24.6 mmol) are added to a solution of bis(2-bromoethyl)dimethylsilane 2(4.0 g, 16.4 mmol) in Dichloromethane (DCM). The mixture is then refluxed for 16 h. Water is added and the aqueous layer is extracted with DCM. It is then washed with 5% sodiumhydroxide (NaOH) solution, dried and concentrated. The product is purified by column chromatography on silica using hexane-ethylacetate mixtures to obtain the product as a colorless liquid 3 (2.1 g) in 59% yield.
