Reaction Steps

Using an analogous procedure to that described in Example 286, 248.7 mg (1 mmol) of 4-chloro-6,7-dimethoxy-3-quinolinecarbonitrile in 10 mL of 2-ethoxyethanol and in the presence of 115.6 mg (1 mmol) of pyridine hydrochloride was reacted with 164.6 mg (1.2 mmol) of 4-amino-2,5-dimethylphenol to give 232.9 mg (66.7%) of the product as a light brown solid, m.p. 234-236° C., mass (electrospray, m/e): M+H 349.9.
