Reaction Steps

To a stirred solution of N-(3,4-dichlorophenyl)-5-((4-nitrophenoxy)methyl)-1,3,4-oxadiazol-2-amine (150 mg, 0.394 mmol) in water (20 mL)/methanol (20 mL), ammonium chloride (211 mg, 3.94 mmol) and iron powder (176 mg, 3.15 mmol) were added and heated to reflux for 4 hours. The reaction mixture was passed though Celite. Solvent was removed under vacuum to obtain 5-((4-aminophenoxy)methyl)-N-(3,4-dichlorophenyl)-1,3,4-oxadiazol-2-amine (0.12 g, 87%). 1H NMR: 400 MHZ, DMSO-d6: δ 5.16 (s, 2H), 5.60 (bs, 2H), 6.62 (d, J=8.40 Hz, 2H), 6.82 (dd, J=2.00, 6.80 Hz, 2H), 7.48 (dd, J=2.40, 8.80 Hz, 1H), 7.61 (d, J=8.80 Hz, 1H), 7.89 (d, J=2.80 Hz, 1H), 11.00 (s, 1H). LCMS: RT 1.66 min. LCMS (ES-API), m/z 351.0 (M+H).
