実験手順

In a 200 ml three necked flask were placed 26 g of p-divinylbenzene and 40 ml of cyclohexane, and to the mixture were further added 40 ml of a cyclohexane solution of an amide-amine complex prepared from 14.8 g of diethylamine and 0.512 g of n-butyllithium. The mixture thus obtained was heated at 50° C. for 3 hours with stirring. Then the reaction solution was added with 10 ml of methanol and subjected to distillation to give 29.0 g of p-diethylaminoethylstyrene having a boiling point of about 84° C./1 mmHg.
