Procedure

Benzene (20 ml) and N,N'-dimethylethylenediamine (1.56 ml, 14.7 mmol) were added to 4-methoxybenzaldehyde (2 g, 14.7 mmol), and the m tture was refluxed under heating for 5 hours while removing the generated water. Benzene was evaporated to give a crude product of 2-(4-methoxyphenyl)-1,3-dimethylimidazolidine.
