In 100 ml of cyclohexane was dissolved 65.0 g of divinylbenzene (a 55% ethylbenzene solution of a mixture of m-divinylbenzene and p-divinylbenzene) and after adding dropwise thereto an amine-amide complex composed of 64.5 g of di-n-butylamine and 25 mmoles of n-butyl lithium, the mixture was heated to 50° C. for 3 hours. To the reaction mixture was added 1 ml of methanol. After concentrating the mixture, 1 g of di-tert-butylcatechol was added to the residue, and then the resultant mixture was distilled under reduced pressure to provide 53.5 g of (di-n-butylaminoethyl)styrene (a colorless liquid having a boiling point of 100.0°-101.0° C./1 mm Hg).
