Obtained by operating as in example 87a, from 7.8g (77 mmoles) of diisopropylamine, 48.2 ml of a 1.6M solution of n-butyllithium in hexane, 6.7 g (70 mmoles) of commercial cyclopentanecarbonitrile, 18 ml of 1,3-dimethylimidazolidin-2-one and 20.5 g (71.4 mmoles) of the compound prepared in example 93c, in 110 ml of dry tetrahydrofuran. After distillation, there is obtained 9.6 g (yield=60.0%) of a viscous liquid. b.p.0.4 =160° C.
