실험 절차

Using an analogous procedure to that described in Example 286, 248.7 mg (1 mmol) of 4-chloro-6,7-dimethoxy-3-quinolinecarbonitrile in 15 mL of 2-ethoxyethanol and in the presence of 115.6 mg (1 mmol) of pyridine hydrochloride was reacted with 320.3 mg (1.2 mmol) of 4-amino-2,6-dibromophenol to give 427.1 mg (89.2%) of the product as a gray solid, m.p.>250° C., mass (electrospray, m/e): M+H 479.7, 481.6.
