A solution of 4-dimethoxymethyl-1-(2-morpholinoethoxy)-2-nitrobenzene obtained in Step 2 (2.97 g, 9.10 mmol) in ethanol (30.0 mL) was added with platinum oxide (0.02 g, 0.10 mmol), followed by stirring at room temperature under hydrogen atmosphere for 2 hours. The reaction mixture was filtered, the solvent of filtrate was evaporated under reduced pressure, the resulting crude product was crystallized from mixed solvent of ethyl acetate/hexane (1/1) to obtain 5-dimethoxymethyl-2-(2-morpholinoethoxy)aniline (0.70 g, 26%).
