In a 500 ml four-neck flask equipped with a stirrer, a reflux condenser, a dropping funnel and a thermometer, 290.3 g (1.43 mol) of N,O-bis(trimethylsilyl)acetamide was placed, and thereto was added dropwise 94.9 g (1.3 mol) of diethylamine from the dropping funnel over a 1-hour period. During the addition, the temperature of the reaction system was kept within the range of 20° C. to 60° C. to make the reaction be proceeding. At the conclusion of the addition, the temperature was raised to 50-60° C. and kept there for 2 hours, whereby the reaction was matured. Then, the reaction product was subjected to vacuum distillation. As the result of this procedure, 152 g of diethylaminotrimethylsilane was obtained as a fraction having a boiling point of 60° C. under the pressure of 80 mmHg. The yield was 90%.
