Procedure

To a suspension of 0.5 g (12.4 mmol) of potassium hydride in tetrahydrofurane, 2.25 g (12.4 mmol) of (2-trimethylsiloxy-ethyl)-cyclopentadiene in tetrahydrofurane is added. The reaction is maintained under stirring for 2 hours and then the volatile compounds are eliminated, leaving an oily solid which is washed with hexane in order to obtain a brown solid. (2.2 g Yield: 81%)
