... under heating of furan with ammonia (amines) above 400 C in the presence of alumina. In a laboratory, the sequence of furan hydrolysis followed by Paal-Knorr reaction with ammonia (amine) is used for this transformation. This sequence can be realized as a two-step procedure or as a domino reaction. ...
