実験手順: 2-Chloroethylamine hydrochloride (73.86 g, 0.70 mol, 1.00 eq) is initially charged in ethanol (2.0 l) in a 4 l three-neck flask with precision glass stirrer, internal thermometer, dropping funnel and reflux condenser, and cooled to −78° C., and sodium ethoxide (226.83 g, 0.70 mol, 1.00 eq, 21% in ethanol) is added. 3-Isocyanatopropyl(triethoxysilane) (173.15 g, 0.70 mol, 1.00 eq) is then added dropwise at −78 to −65° C. within 3 h and then the mixture is heated to 50° C. Potassium thioacetate (79.95 g, 0.70 mol, 1.00 eq) is added in five portions and the mixture is heated to reflux. After a reaction time of 4 h, the mixture is cooled to room temperature and the suspension is filtered. The filtrate is freed of the solvent on a rotary evaporator and dried under reduced pressure. The (EtO)3Si—CH2CH2CH2—NH—CO—NH—CH2CH2—S—CH2CH3 product (288.02 g, quant.) is obtained as an orange oil. reflux condenser the mixture is heated to 50° C the mixture is heated to reflux After a reaction time of 4 h, the mixture is cooled to room temperature the suspension is filtered The filtrate is freed of the solvent on a rotary evaporator dried under reduced pressure

実験手順: 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.
