3-Chloroaniline → 4-[(3-Chlorophenyl)amino]-6,7-dimethoxyquinoline-3-carbonitrile

Participants

Reaction Steps

A mixture of 0.5 g of 4-chloro-6,7-dimethoxy-3-quinolinecarbonitrile, 0.51 g of 3-chloroaniline, 0.16 ml of pyridine, and 6 ml of ethoxyethanol was stirred under nitrogen, at reflux temperature for 6 h. The mixture was cooled and partitioned with dichloromethane and aqueous sodium bicarbonate. The organic layer was washed with water, dried and evaporated. The residue was recrystallized from ethyl acetate-hexanes to give 0.37 g of 4-[(3-chlorophenyl)amino]-6,7-dimethoxy-3-quinolinecarbonitrile as a solid, mp 214-217° C.
