Reaction Steps

A mixture of 6-butoxy-4-chloro-7-(2-methoxyethoxy)-3-quinolinecarbonitrile (184 mg, 0.55 mmol), 2,4-dichloro-5-methoxyaniline (127 mg, 0.66 mmol) and pyridine hydrochloride (76 mg, 0.66 mmol) in 5 mL of 2-ethoxyethanol is heated at 120° C. for 7 hours. The reaction mixture is cooled to room temperature and concentrated in vacuo. Diethyl ether is added to the residue and the solids are collected and suspended in saturated aqueous sodium bicarbonate. After stirring for 1 hour the solids are collected by filtration and washed with water. Purification by preparatory thin layer chromatography, eluting with 7% methanol in dichloromethane provides 93 mg of 6-butoxy-4-[(2,4-dichloro-5-methoxyphenyl)amino]-7-(2-methoxyethoxy)-3-quinolinecarbonitrile, mp 166-167° C.
