Iron can also be used as a reducing agent. The reaction is in Presence of an acid such as e.g. B. acetic acid or ammonium chloride where appropriate Added a solvent such as water. It can be beneficial before Reduction to introduce the ester group. In the presence of several nitro groups in the Molecule can also selectively the desired ortho-standing nitro group in a conventional manner can be reduced with Na₂S.
