In a manner like that used for the preparation of alpha-bromoethyltriethoxysilane, alpha-bromoamyltriethoxysilane is prepared in two steps from amyltrichlorosilane (commercially available). One-quarter mole of alpha-bromoamyltriethoxysilane (78.5g) is refluxed for 12 hours with 0.25 moles (33.75g) of benzyldimethylamine in 125 ml. of 2-butanone. The product, alpha-(benzyldimethylammonio)ethyltriethoxysilane bromide is isolated by removing the solvent under vacuum.
