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.
