3-Aminodibenzofuran is a building block used as a reactant in the preparaton of dibenzofuryl(phosphonomethyl)alanines as endothelin converting enzyme inhibitors.

Synthesis of Schiff base
Ethanolic solutions of 3-aminodibenzofuran and 2-furan carboxaldehyde in 1:1 molar ratio were mixed and refluxed over a water-bath for 3 hours. The resulting Schiff base that separated out on cooling the mixture was filtered, washed with ethanol and air-dried.
