3-Chloro-4-(pyridin-2-ylsulfanyl)aniline → 4-[3-Chloro-4-(pyridin-2-ylsulfanyl)-phenylamino]-7-fluoro-6-methoxyquinoline-3-carbonitrile

Participants

Reaction Steps

Following the procedure of Example 1, a mixture of 635.4 mg (2.68 mmol) 4-chloro-7-fluoro-6-methoxy-quinoline-3-carbonitrile, 642.1 mg (2.81 mmol) of 3-chloro-4-(pyridin-2-ylsulfanyl)-phenylamine and 309.8 mg (2.68 mmol) of pyridine hydrochloride are refluxed in 2-ethoxyethanol (27 mL) at 100° C. for 12 hours to yield 4-[3-chloro-4-(pyridin-2-ylsulfanyl)-phenylamino]-7-fluoro-6-methoxyquinoline-3-carbonitrile as a yellow solid, mp 225-228° C.
