Reaction Steps

To a single-neck reaction flask (500 ml) were added 4-chloro-6-nitro-7-(tetrahydrofuran-3-yl-oxy)quinoline-3-carbonitrile (5 g, 15.649 mmol), 3-chloro-4-(pyridin-2-yl-methoxy)benzenamine (4.037 g, 17.214 mmol) and pyridine hydrochloride (421 mg). To the flask was added isopropanol (150 ml). The mixture was stirred and refluxed for 2 hr at the temperature of 85° C. The reaction was stopped and cooled to the room temperature. The resultant mixture was filtered in vacuo. The filter cake was washed with mother liquor and dried in vacuo to give a yellow solid (5.988 g). Yield: 73.9%.
