Procedure

36.0 g of the thus obtained 4-(2-(4-ethoxyphenyl)ethenyl)-1-n-pentyl-1-phenyl- 1-silacyclohexane was dissolved in 100 ml of ethyl acetate, followed by hydrogenation at a pressure of 5 kg/cm2 of hydrogen at room temperature in the presence of 200 mg of palladium-carbon used as a catalyst. After the hydrogen had been consumed theoretically, the catalyst was removed by filtration and the resultant flitrate was concentrated to obtain 36.2 g (quantitative yield) of 4-(2-(4-ethoxyphenyl)ethyl)-1-n-pentyl-1-phenyl-1-silacyclohexane.
