Reaction Steps

A stirred mixture of 4-chloro-6,7-dimethoxy-3-quinolinecarbonitrile (3.73 g, 15 mmol), 1,3-diaminobenzene (4.86 g, 45 mmol), pyridine (1.21 ml, 15 mmol), and 45 ml of ethoxyethanol was refluxed for 30 m, cooled, and stirred with aqueous sodium bicarbonate. The resulting solid was filtered, washed with water, and dried. Recrystallization from ethanol gave a brown solid, mp 222-228° C.
