Upon completion of reaction, after removing the solvent through distillation under reduced pressure and extracting with water and diethyl ether, the product was dissolved in dichloromethane (200 mL). After adding triethylamine (1.0 mol) and trimethylchlorosilane (0.8 mol), the mixture was stirred for a day at room temperature. Upon completion of reaction, after removing the solvent through distillation under reduced pressure, 0.342 mol (yield: 86%) of the target compound was obtained by extracting with water and diethyl ether. 1H and 13C NMR spectroscopic data of the purified N,N-bis(trimethylsilyl)-2-(3-(trimethoxysilyl)propoxy)ethanamine are as follows.
