When the addition was complete the reaction mixture was heated under reflux for 18 hours. The solvent was evaporated off under reduced pressure and the residue was extracted with ethyl acetate, washed with saturated aqueous ammonium chloride solution and dried (MgSO4). The solvent was evaporated off under reduced pressure to give 1-[2-amino-3-[(4-methoxyphenyl)methoxy]propyl]-1H-imidazole as an oil (3.6 g) which was used directly without further purification.
