Reaction Steps

A mixture of 2.2 g of reduced iron, 0.5 ml of conc. hydrochloric acid and 2.5 ml of water was added to a solution of 2.2 g of ethyl o-nitrocinnamate in 30 ml of ethanol. After heating under reflux for 1 hour, insoluble matters were filtered off and the filtrate was concentrated under reduced pressure. An aqueous sodium hydrogen carbonate solution was added to the residue followed by extraction with toluene. After the extract was washed with water and dried, the solvent was distilled off to obtain 1.6 g of ethyl o-aminocinnamate as yellow crystals.
