At room temperature, 22.3 g (0.22 mol) of triethylamine was added dropwise over one hour. At the end of dropwise addition, the flask was heated at 80° C. After the internal temperature became constant, 47.0 g (0.20 mol) of thexyldiisopropylchlorosilane was added dropwise over two hours. After the completion of dropwise addition, the reaction solution was stirred for 5 hours at 80° C. The reaction solution was then cooled to room temperature, and the resulting hydrochloric acid salt removed by filtration. The filtrate was distilled, collecting 38.6 g of a fraction having a boiling point of 87-92° C./0.13 kPa.
