Hydrochloric Acid → (E)-Stilbene-3-amine

Participants

Reaction Steps

A mixture of (E)-3-nitrostilbene (3.63 g), hydrochloric acid (35%, 10 ml) and iron powder (3.6 g) in ethanol (30 ml) was refluxed for 1 hour. The mixture was poured into aqueous sodium bicarbonate solution and extracted with ethyl acetate twice. The combined organic solution 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 (E)-3-aminostilbene (2.05 g).
