1,2-Ethanediamine, N1-(3-(triethoxysilyl)propyl)- → 1H-Imidazole, 4,5-dihydro-1-[3-(triethoxysilyl)propyl]-

Participants

Reaction Steps

53.2 g of ethyl orthoformate (0.36 mol) is added at +20° C. to 80 g of N-(2-aminoethyl)-3-aminopropyltriethoxysilane (0.3 mol). The temperature of the mixture is brought up to reflux until formation of ethanol is no longer observed. The reaction mixture is then distilled under partial vacuum (2-5 mbar) and the desired product (69.1 g) is recovered (temperature: 130-135° C.)
