Reaction Steps

3-Thiophenecarbaldehyde (22.43 g) was dissolved in toluene (200 ml) and N,N'-dimethylethylenediamine (22.3 ml) was added. The mixture was stirred for 16 hours with removing azeotropic water under reflux by Dean-stark trap. The reaction mixture was concentrated under reduced pressure and the residue was distilled under reduced pressure to give 1,3-dimethyl-2-(3-thienyl)imidazolidine (5.88 g).
