3-Amino-1-propanol → (3-Aminopropoxy)(tert-butyl)dimethylsilane

Participants

Reaction Steps

A solution of 7.4 g (98 mmol) 3-aminopropanol in 10 ml THF was added at room temperature to a suspension of 4.12 sodium hydride (60%; 103.2 mmol) in 140 ml THF. The mixture was stirred for 1 hour and then 16.28 g (108 mmol) tert-butyl-dimethylsilylchloride was added and vigorous stirring was continued for 1 hour. The mixture was diluted with 300 ml diethylether and washed successively with 100 ml of aqueous K2CO3 (10%), 100 ml of water and 100 ml of brine, dried over MgSO4 and evaporated to give 17 g of light yellow crude product. This product was dissolved in ethyl acetate/hexane 1/10 and filtered through a pad of silica gel. The filtrate was concentrated in vacuo to give 13 g (70%) of the desired product as a colorless oil.
