実験手順

Using an analogous procedure to that described in Example 286, 248.7 mg (1 mmol) of 4-chloro-6,7-dimethoxy-3-quinolinecarbonitrile in 12 mL of 2-ethoxyethanol and in the presence of 115.6 mg (1 mmol) of pyridine hydrochloride was reacted with 210.0 mg (1.3 mmol) of 4-aminoresorcinol to give 330.4 mg (98.0%) of the product as a deep purple solid, m.p.>250° C., mass (electrospray, m/e): M+H 337.9.
