Reaction Steps

A mixture of methyl 4-(3-nitrophenyl)benzoate (8.37 g), iron powder (7.5 g) and hydrochloric acid (35%, 22 ml) in methanol (60 ml) was stirred under reflux for 3 hours. Then the mixture was poured into aqueous sodium bicarbonate and extracted with ethyl acetate twice. The combined organic phase was washed with aqueous sodium bicarbonate and brine, dried over magnesium sulfate and concentrated. The resultant solid was collected and washed with isopropyl ether to give methyl 4-(3-aminophenyl)benzoate (5.33 g).
