Procedure

A ten gram sample of N"-[2-hydroxy-3-[3-(trimethoxysilyl)propoxy]propyl]-N,N,N',N'-tetramethylguanidine, prepared in Example 2, was dissolved in 5 g of toluene. To this solution was added, under a stream of argon gas, 7.1 g of 3-isocyanatopropyltriethoxysilane. The resulting mixture was stirred at ambient temperature for one hour. At the end of this time, analysis of the reaction mixture by infrared spectroscopy indicated the absence of hydroxyl function. The reaction mixture, containing 71% by weight of [3-(triethoxysilyl)propyl]carbamic acid, [2-[[bis(dimethylamino)methylene]amino]-1-[[3-(trimethoxysilyl)propoxy]methyl]ethyl]ester, was used without further puriofication as an accelerator.
