In a 2-liter flask were charged 50 g (0.43 mol) of indene and 600 ml of dry n-hexane, to which was dripped down 270 ml of a hexane solution of 1.6 M n-butyllithium at 0° C. The mixture was stirred at room temperature for 10 hours, to which was added 111 g (0.86 mol) of dimethyidichlorosilane and the mixture was stirred as was at room temperature for 3 hours. After it was filtered through a G-4 filter, the reaction mixture was distilled under reduced pressure to remove volatile components. The crude product thus obtained was purified by distillation under reduced pressure (100° C., 7 mmHg) under argon atmosphere. As a result, 78 g of the target compound was obtained. Yield: 87%.
