DOI: 10.1080/00397911.2016.1277761
Abstract: ABSTRACT An efficient, catalyst-free, microwave-assisted approach has been developed for the synthesis of 2-aryl/alkyl-3-(1H-benzo[d]imidazol-2-yl)-2,3-dihydroquinazolin-4(1H)-one derivatives by condensing 2-aminobenzamides with various aliphatic, aromatic, and heterocyclic aldehydes. This catalyst-free approach exhibited good functional group compatibility and produced… read more here.
