Procedure
The solution of p-methoxyphenylacetaldehyde in 200 ml of toluene, prepared according to Example la), is added under reflux within one hour to a mixture of 78 g (55.5 mmol) of N-methyl-2-(cyclohexen-1-yl)ethylamine in 20 ml of toluene. After 1 hour under reflux there is obtained N-[(E)-p-methoxystyryl]-N-methyl-2-(cyclohexen-1-yl)ethylamine (yield 95.3%) dissolved in toluene.
