Reaction Steps

A mixture of ethyl 2-methyl-5-(4-nitrophenyl)-3-furanecarboxylate (500 mg, 1.82 mmol), iron powder (325 mesh, 811 mg, 14.5 mmol) and aqueous 1 N HCl solution (0.36 mL, 0.36 mmol) in EtOH (5 mL) was heated to reflux for 2 h. The reaction mixture was filtered and concentrated under reduced pressure to give the title compound (396 mg, 89% yield) as a brown oil.
