It is usually prepared by reduction of
2-nitrobenzaldehyde with iron or
iron(II) sulfate. Like related
aminoaldehydes, it is unstable with respect to
self-condensation. 2-Aminobenzaldehyde is used to prepare
quinolines by the
Friedländer synthesis: By
template reactions, it also forms trimeric and tetrameric condensation products that have been studied as
ligands. ==References==
