Procedure

A stirrer bar was put into a 50 ml two-mouth eggplant flask equipped with a thermometer and a calcium chloride tube. The flask was charged with 5.13 g (40 mmol) of allyl valerate (manufactured by Aldrich Co.) and 0.2 g of a platinum catalyst (“BY 24-835” manufactured by a Toray-Dow Corning Co.). Then, 4.89 g (40 mmol) of trimethoxysilane (manufactured by Tokyo Kasei Kogyo Co., Ltd.) was added while stirring and controlling the temperature at 50° C. or less. After further addition of 0.2 g of the platinum catalyst, the mixture was reacted at room temperature for six hours. After completion of the reaction, the reaction mixture was distilled under reduced pressure using a Kugelrohr distillation apparatus to obtain 8.12 g of 3-trimethoxysilylpropyl valerate of the silane compound (1).
