Reaction of cyclopentadienyllithium II1 with N-phenylaziridine III1 to give N-(2-cyclopentadienylethyl)aniline IV1 ##STR8## 0.36 g (5 mmol) of cyclopentadienyllithium was added in several portions to a solution of 0.6 g (=5 mmol) of N-phenylaziridine in 50 ml of tetrahydrofuran (THF) under an argon atmosphere at -30° C. After the addition was complete, the mixture was stirred at -30° C. for 1 hour and then warmed to room temperature over the course of 12 hours. Then 50 ml of a saturated aqueous NH4Cl solution were added, the mixture was stirred for 1 hour and the organic phase was separated off. The latter was dried over anhydrous Na2SO4 and filtered, and the solvent was removed under oil pump vacuum. 0.83 g (4.5 mmol, 90% of theory) of IV1 was obtained as a yellow oil.
