Versuchsvorschrift
4,6-Dichloro-8-methoxy-quinoline-3-carboxylic acid ethyl ester (250 mg, 0.83 mmol) was treated with cyclopentylamine following general procedure B to afford 6-chloro-4-cyclopentylamino-8-methoxy-quinoline-3-carboxylic acid ethyl ester (240 mg). Thus obtained amino-ester was hydrolyzed to the corresponding acid in quantitative yield using general procedure D and then transformed into the corresponding ethylamide (170 mg) following general procedure E.
