Aminopropyltrimethoxysilane (0.398 mol) and triethylamine (100 mL) were dissolved in dichloromethane (200 mL) in a round-bottom flask and trimethylsilyl chloride (0.800 mol) was added in a dropwise manner. After the addition was completed, the mixture was stirred at room temperature for 24 hours. Upon completion of reaction, N,N-bis(trimethylsilyl)aminopropyltrimethoxysilane (yield: 89%) was obtained through concentration under reduced pressure and fractional distillation. 1H and 13C NMR spectroscopic data of the purified N,N-bis(trimethylsilyl)aminopropyltrimethoxysilane are as follows.
