Procedure
100 g of p-methoxycinnamic acid (Aldrich) was dissolved in 500 mL of toluene and 118 g of dicyclohexylcarbodiimide (DCC) (Aldrich) was added. After adding 100 g of hydroxymethyltriethoxysilane (Gelest), the toluene solution was stirred for about 18 hours at about 40° C. After evaporating the solvent under reduced pressure and adding 200 mL of acetone, insoluble byproduct (dicyclohexylurea) was removed by filtering. After removal of acetone, triethoxysilylmethyl-(p-methoxycinnamate) was obtained. The new product could be identified by thin-layer chromatography.
