Investigation of amination in 4-chloro-2-phenylquinoline derivatives with amide solvents

Add time:08/26/2019    Source:sciencedirect.com

Novel 4-amino-2-phenylquinoline derivatives were synthesized by reacting various 4-chloro-2-arylquinoline compounds having activated chloro group with the corresponding amide solvents at reflux for overnight. The activity of amination by the amide solvents depended on the competition between the steric and electronic effect of the N-substituents on the amino group. Their activities were shown as N,N-dimethylformamide>N,N-diethylformamide>N-methylformamide>formamide>N,N-dimethylacetamide>N,N-dimethylpropionamide. The yields for the amination products seemed proportional to the ease of the dissociation of the amides.
