Conditions

Temperature: 103.5 °C

Procedure

A mixture of 12.0g of gamma-bromopropyltrimethoxysilane and 14.15g of octadecylmethylamine are heated at 94-113° C. for 16 hours and then cooled. The resulting tertiary ammonium salt is dissolved in 100 ml of absolute ethanol and 0.05 moles of freshly prepared sodium ethoxide in 50 ml of ethanol is added. Filtration of the resulting solution and removal of the solvent yield the tertiary amine, gammamethyloctadecylaminopropyltrimethoxysilane.
