Procedure
To 7.33 g of (2-trimethylsiloxy-ethyl)-cyclopentadiene in ether, 16 ml of a 2.5 M butyllithium solution in hexane (40 mmol) is added. The addition is realised at −78° C. The immediate formation of a white solid and butane evolution are observed. It is maintained reacting for 3 hours. Then it is dried; the resulting solid washed with hexane, leaving a powdery white solid. (6.19 g, 33 mmol, Yield: 82%).
