Procedure: To a stirred pre-warmed solution of (S)-(+)-S-methyl-S-phenylsulphoximine (3 g, 18.7 mmol) in acetonitrile (2 mL) at 65° C. was added (trimethylsilyl)diethylamine (4.12 g, 21.1 mmol) dropwise via a syringe. The reaction was maintained at 65° C. and stirred for 3 hours. Additional amount of (trimethylsilyl)diethylamine (2 mL, 10.2 mmol) was added and the reaction mixture was stirred at 65° C. overnight. The reaction was then concentrated under reduced pressure and dried under vacuum to give the title compound. This material was used directly in next step of the synthesis without further purification. the reaction mixture was stirred at 65° C. overnight The reaction was then concentrated under reduced pressure dried under vacuum

Procedure: In a 1 liter four-neck flask equipped with a stirrer, a reflux condenser, a dropping funnel and a thermometer were placed 108.5 g (1.0 mol) of trimethylchlorosilane, 111.1 g (1.1 mol) of triethylamine and 300 ml of hexane. Thereto, 73.0 g (1.0 mol) of diethylamine was added dropwise 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 mixture was filtered through a glass filter to remove the salt yielded as a by-product. The filtrate was allowed to stand for one day at room temperature to precipitate the salt. The salt precipitated was filtered off, and the filtrate was subjected to distillation under ordinary pressure to obtain 136.3 g of diethylaminotrimethylsilane as a fraction having a boiling point of 125-126° C. The yield was 94%, and the chlorine concentration was 146 ppm.

Procedure: 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%.
