Reaction Steps

Using an analogous procedure to that described in Example 274. A reaction mixture of 250.0 mg (1.1 mmol) of 4-chloro-8-methoxy -3-quinolinecarbonitrile, 131.7 mg (1.1 mmol) of pyridine hydrochloride and 286.7 mg (1.3 mmol) of 4-bromo-3-hydroxy-aniline in 10 mL of 2-ethoxyethanol was heated at 100° C. for 1.5 hr. The work up gave 374.1 mg (88.6%) of the product as a pink solid, m.p. 146° C. (dec.), mass spectrum (electrospray, m/e): M+H 369.9.
