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, 273.3 mg (3.0 mmol) of pyridine and 261.4 mg (1.25 mmol) of 3-dimethylaminoaniline hydrochloride in 10 mL of 2-ethoxyethanol was heated at 100° C. for 1.5 hr. The work up gave 294.8 mg (73.4%) of the product as a deep greenish yellow solid, m.p. 222-225° C., mass spectrum (electrospray, m/e): M+H 319.0.
