After stirring the mixture for one hour at 80° C., 200 ml of ethyl acetate and 200 ml of water were added to the reaction mixture and the ethyl acetate layer was extracted. The ethyl acetate layer was washed with 200 ml of water and concentrated to remove ethyl acetate to provide 2-(2-(2-(3-nitrophenoxy)ethoxy)ethoxy)ethanol (1-A).
