A mixture of 200 mg (0.88 mmol) of 1-[(2-methoxyethoxy) methoxy]-4-nitrobenzene (21), 100 mg of 10% Pd/C and 550 mg (8.7 mmol) of ammonium formate in 10 mL of absolute ethanol was stirred at room temperature for 18 hours. The reaction mixture was diluted with 100 mL of absolute ethanol and passed through a small pad of celite. The filtrate was concentrated and purified by silica gel column chromatography using 8:2 ethyl acetate:hexane as the eluent to yield 130 mg (0.65 mmol, 75%) of 4-[(2-methoxyethoxy)methoxy]benzenamine (22). NMR, IR and MS data confirmed compound identity.
